Improves Horsepower. This SR Performance Cold Air Intake kit completely replaces the stock air box and restrictive paper filter element in your 1999-2004 3.8 & 3.9 V6 Mustang with a high flow filter assembly for a noticeable increase in horsepower and throttle response while filtering out destructive power robbing dust particles. This CAI pulls cooler denser air from inside the inner fender well to make more power that you can feel.

Reusable Filter. This kit includes a high flow reusable air filter, so there's no need to go out and buy a new filter every few thousand miles. Just clean the filter, re-oil it, save money, and go!

Polished Finish. A SR Performance Cold Air Intake not only improves horsepower and acceleration, but it also improves your Mustang's underhood appearance with a striking polished aluminum finish. Now you can have the best of both worlds, performance and style.

Simple Install. SR Performance Cold Air Intake kits are relatively easy to install with basic hand tools. No extra modifications are required for the installation.

Review & Install Video

Hey everyone I’m Justin with and I’m taking a look at this polished aluminum cold air intake kit for all 99-04 V6 Mustangs. We’re going to show you what kind of horsepower and torque numbers you can expect, when using this very budget friendly intake. This kit replaces your somewhat restrictive factory airbox with everything you see here, including the washable high flow filter, polished aluminum intake tube, heat shield, and all necessary hardware. Besides giving you a nice boost in power and sound, this kit is sure to give you a nice visual improvement under the hood as well, thanks to that polished aluminum finish. Cooler, denser air results in more horsepower, that’s a fact. With that in mind this kit puts your filter right in your fender well, giving you maximum cool air, especially when combined with the supplied heat shield. We want to see what kind of improvements this kit is going to make on our 2000 V6 back there, but before we go bolting everything up we want to get a baseline number down first, to see what we’re working with. Our automatic V6 put down a less than exciting 146 horsepower, and 170 ft/lbs of torque, in stock form, now we’re going to install our polished cold air intake system, which should only take about an hour, thanks to the fact that this kit includes all hardware needed for install. The only exception is for you folks out there whose car isn’t equipped with an air temperature sensor, located right here. If you’re one of those few, don’t worry, simply go to your local hardware store, pick up a rubber plug that shouldn’t cost you more than a buck or two, and plug the hole, problem solved. In addition to installing our cold air intake, we’re also going to upload our custom 93 octane Bama tune, and maximize our gains. This is going to optimize our spark timing, perfect those air/fuel ratios, and give you drastically improved throttle response. Alright, so now the moment of truth, with our intake installed and our Bama tune uploaded, let’s turn the rollers one more time and see the improvements this intake made on our V6. The numbers are in and we’re very happy with the results. Our polished cold air intake equipped V6 put down a total of 164 horsepower, and 194 ft/lbs of torque, making for an impressive peak gain of 18 horsepower over our baseline numbers. We were also able to pick up some very nice power throughout the curve as well, making 19 horsepower, and 27 ft/lbs of torque respectively. Not only do we pick up more horsepower and torque with this intake, but we improved our under the hood appearance and added a nice little growl to the motor as well. So even though this intake doesn’t have a big brand name stamped all over it, it certainly held up its end of the bargain and made some solid gains.

Start up and idle hiss....? On my install, this CAI puts out a loud hissing sound that varies with the A/C compressor cycling. When under load, it sounds mean, but at idle it sounds loud and unnatural. Any suggestions?


  • The hissing noise is due to the increase air demand/flow during that initial start up and especially with the added load of an A/C compressor. It in completely normal and as you said, sounds kinda mean.

does it really give you 19 rwhp or is that only with a tune?


  • 19 HP without a tune probably won't happen. Maybe you could get 10 HP with perfect conditions.

CAI vs. K&N Filter Alone My car currently has a K&N filter attached to the factory intake tubing. I was wondering if I can expect any real gains from purchasing the kit to replace the intake tubing? I understand the theory behind installing smooth intake tubing, I was wondering if anyone has experience with a detectable difference between the two, or dyno results to back this up.


  • Adding a K&N filter in my experience has never produced any real significant increase in HP and TQ. You have a nice filter sure, but the stock parts are still there. If you're looking for increase and actual gain it's a safe bet to go with the whole system. Keep in mind that you wont notice a gain out of the Cold Air Intake unit until you use a tuner to tune it.

Can I install a different filter in it, say like a kn?


  • You can use any cone type filter that is the approximate dimensions of the filter that comes with the kit. That being said you don't need to replace the filter all you need to do is clean it and re-oil it. You can buy the kit much cheaper than buying new filters. Hope this helps

    I'm a 19 year old girl and I was able to install this by myself, so you can do it too. It does fit the 04 but I had to buy a rubber plug/stopper to cover the hole for the sensor my car doesn't have, which was at the hardware store for a whopping 22 cents (brought the pipe in to get the right size). Looks awesome under the hood and I love the sound it makes! I drive around without music sometimes just to hear it taking in all that air :)

    Great product. Easy to install following along the video, which the video is spot on. I have a 2000 3.8L and dual exhaust. I never knew how restricted the exhaust sounded until today after I put the CAI on. It just feels like the air just runs straight and clean into the engine. I get a nice little whoosh of air around the 3,000 RPM mark, kinda sounds like a turbo for a second, then it goes away. Doesn't annoy me at all, I can only hear it with the windows up anyways. I wasn't sure if I was supposed to hear it so I check all my couplings and hose clamps and they are as tight as they'll go so I take it that it's part of deal. Took me about an hour to do. That little hose end piece can be tricky, just use the screwdriver real good, but don't do it too much :) Noticed a much better throttle response and a little more power. Can't beat it for bolt on under $100. Don't think about it, just do it Stang owners.

    great mod for a low price

    alright let me say this. make sure that your mustang has hoses that aren't dryrotted, but the hose provided in the kit fixed the issue with the help of a small hardware clamp. the installation was tedious but I did it making sure the product would function right. the start up was a little louder not to much and the idle was more aggressive. it wasn't until I hit the street did the throttle and the acceleration kicked in. Thanks AM if financials weren't a worry I'd be your best customer!!

    I installed this on my 2004 Mustang V6 3.9L. No problems installing, all i had to spend extra on was on a small rubber clamp hose($3) for the new hose they provided in the kit. Took about an hour or so, had brother and friends help, totally worth the money. No need to spend extra on bbk unless you want a brand.. over all, another satisfaction from american muscle.

Thought it over many times between bbk and this, same difference in the end plus a money saver! This intake does work for 2004 V6 Mustang 3.9L. Only extra expense i had to do was buy a small hose clamp to fit with the new hose they provided in the kit which was $2? Overall, satisfied .

    Purchased this kit for my 2002 mustang and with the excellent support videos had the old airbox out and the new CAI in in no time. The difference is instantly noticible. Sounds great and really boosted the response. Had a brand name on my other car and there is absolutely no need to pay more when this product is just as well made and performs just as well for a great price. Thanks AM!

    This will help all you newbies

    Okay guys I have read most of your reviews and I love hearing all the pros, and not liking most of the cons, your not giving this product any credit. Let's start by letting you know about the hole covering issue, most plug it in....simple. Others like myself by the little air filter from autozone. Now as far as the black hose that is included, yes it is bigger than the stock, but check this out it does fit the intake, and as for the opposite side where you connect the plastic peace that goes to the engine from the old hose, just wrap some aluminum paper around the tube, this will make the adapter thicker thus letting the hose fit in nice and tight, just add or remove aluminum as needed. Not too hard to do. I love the product, just as good as the brand names and I love the added boost and sound. AM Rocks, have fun my mustang friends....

    Wow, Amazing

    If you're still running your stang with the stock air filter, you are really missing out. This was the first upgrade I made to my '99 and I am nothing but happy for doing it. Way more throaty in sound, acceleration greatly increased, and looks boss under the hood. I would recommend to everyone who is looking to modify your ride. Great product. Good job American Muscle, I will be returning.

    Great Product - Easy Install

    I got my parts powder coated in a gloss black ($60) and it looks like a factory part. It was a bit of a challenge getting it to fit, but it is the perfect size and does install like it belongs in there. The provided hose was too big on the engine block side but a $1.50 clamp fixes that. The install video was RIGHT ON!!!

    Just finished driving around after installing this CAI. While it was for sure not as easy as the pro who install it in the video makes it look, it wasn't bad. Considering I hadn't ever changed oil or a spark plug I cant complain! Definitely has a gutsier sound now and seems a bit more responsive. Great fun and well worth the minimal investment! Do it now!

    This WILL fit a 2004 3.9L V6 "A 3.9 L (237 cu in) version of the Essex V6 was introduced in 2004. It used the same 3.810 in bore diameter as the 3.8 L Essex, but had a slightly longer 3.464 in (88.0 mm) stroke.[7] It was installed in a running change on later production 2004 Mustangs (starting October 7, 2003), though overall engine output was identical. Ford marketing information says that the bore is 3.8 inches and that the displacement is 3802 cc (232 cu in).[8] The bore and stroke, however, work out to 3883 cc (237 cu in). Use of the 3.9 was short-lived in the Mustang though as it was replaced by Ford's 4.0 L Cologne OHC V6 when the Mustang was redesigned for 2005. The 3.9 continued on in the Ford Freestar minivan (successor to the Windstar) for a few years until production of the engine was discontinued in 2007." Throttle bodys for the 3.8L and 3.9L are identical with the same Ford part number

    Great product

    CAI is awesome for the price I can hear the air as I drive get sucked through the filter. However, the hose that was provided fits their product but not the nipple that fits on the valve cover. The best thing I found to fill the extra hole if your 'stang doesn't have the addt'l sensor is a 1/4" Rubber Vacuum Cap that you can pick up at Napa or O'reilly's.

    Good Product, Missing an Important Part

    My car: 2002 V6 Mustang, Stock except Cold air intake and Magnaflow Catback exhaust. I want to complain about this product before I compliment it. Firstly, no where on this website did American Muscle think it was important enough to mention that one might want to check and see if their car actually has an air temperature sensor on their car. Why is this a problem? Because there's a hole in this product's piping where you're supposed to plug in the air temperature sensor, and if your car is like mine and doesn't have one, then you have to find a way to plug this hole or unfiltered air can make its way into your engine and that's not good. Not a huge deal because I just went to Lowe's and got a rubber cork, removed the rubber piece that comes with the kit, and used the cork to seal off this hole. This part cost me 99 cents, so why they couldn't include it in the kit, just in case, is questionable. That said, when I called American Muscle about the problem, they noted that a lot of people have this issue and they plug it with one thing or another. Well, why not put a notice on the website? Not a huge deal, but this did keep me from giving the product a 5 star rating. Just a little notice on the website would have saved me a huge headache when I installed the kit today. My advice to people looking to buy this product: check and see if you have an air temperature sensor. The easiest way to do this is to look on your intake assembly and see if there are two electrical cables running to the assembly. Each sensor requires its own cables, so if you only see one then plan on making a trip to a hardware store to buy a rubber plug. The good? I noticed that the throttle is a little more responsive. It's not a huge difference, but the car seems to get a little more low end power. My favorite part about the new intake is the sound. You won't really hear it until about 2000 rpm or more, but there's a audible rumble coming from under the hood that I didn't hear before. Watch the installation video, and at the end it shows you exactly what to expect. Decent product, and aside from that relatively minor issue, I'm happy.

    Good for what you pay.

    When I bought it I paid $50. So after everything, I paid only $50 + self install. A tank of gas is $50 now. So price is cheap. Still had to do some minor work and repair on it. It came slightly damaged. a 1 hour install took 3 do to extra work. CONS -The generic rubber covers for this vs the BBK makes things kinda "not so gentle" to put together in the end. Not much room to move. There was no instructions or parts list with the shipment. Ok I can accept that. use the Internet. gotcha. -The long pipe was bent at the screw holes on one corner by about 40degrees plus had some dings and sharp edges around where the gasket went. Needed a ball peen hammer to flatten it out and used a high torque dremel to sand the rough edges. -Short pipe didn't line up at all with the throttle body. Its off center by about and inch. -The air temperature sensor would NOT fit in the rubber grommet by itself. Ended up sanding out the inside by 2/16ths" and then cutting around the insert groove of the grommet to give it enough space to even get the head in. Extra parts with no idea where they go. This is personally annoying. But *shrugs* -do to odd alignment the common CAI suction and whistling sounds are loud. Louder then they should be. (I'll try reinstalling again for the 3rd time tomorrow) PRO's -Instant pick up compared to the stock. -My fuel is burning more efficiently. I can feel my torque at low to mid range. -Opened up my right side of the engine bay. -Even after the hassle and added work to get it to fit and work correctly(outside of the louder then a normal CAI sound I gets) Worth the $50. -Cheaper then the BBK and the K&N.

    Air Intake

    I bought this air intake about 5 months ago. The difference in throttle response is like night and day. Did have issues with the product fitting tightly. It would slip from the back side of the mass air flow housing because its just a little bit too short. I have 3 hose clamps,super tight on the back side of the MAF and 2 on the throttle body. Beside the throttle response it made the flowmasters a little louder and deeper. Be careful while installing it, the "chrome" scratches easy, but overall its a good intake.

    I've really enjoyed this product. It was easy enough for my 16 year old son to install by himself. One major problem in CA, it won't pass the smog test. It doesn't have a Carb EO #. Fortunately I saved the original system, but still a pain to have to remove this system just to get it smogged.

Quick and easy to put in and has a noticeably deeper sound and better throttle response. I had a full exhaust on my '00 v6 and it sounds so much better.
