Review & Installation Video

Hey everyone, Justin from AmericanMuscle.com here and today I have the cold air intake system from Airaid for all 99-04 Mustang GTs. Airaid has become one of the heavy hitters in terms of producing performance intakes and checking out this kit here today, it’s easy to see why, that quality construction and that sleek black appearance have made it one of our customer favorites. This kit from Airaid completely replaces your factory intake using everything you see here, you’ll receive the large diameter intake tube, plastic heat shield, reusable high flow filter, and all the hardware and couplers needed for install. Besides looking great under the hood, this kit is going to make more power and torque and actually increase your fuel efficiency as well, which is always a nice little bonus. You don’t have to run a tune when running this intake from Airaid, but we like to recommend pairing it up with one of our custom Bama tunes, to get the most power out of your car. Now let’s get that restrictive airbox out of there and install this kit from Airaid. This is something any backyard mechanic should be able to tackle in about an hour’s time using standard hand tools. In addition to installing the Airaid we’re also going to upload our custom 93 octane Bama tune, in hopes of really making some power with our cold air. This is going to optimize our spark timing, tweak those air/fuel ratios, and give us improved throttle response, and for automatics we’re also going to see increased shift firmness, and adjusted shift points. Now that we have our intake and our tune installed on our GT let’s run it one more time on the Dynojet, and see just how much power we were able to squeeze out of this combination. So our baseline run with our automatic 2000 GT gave us 222 horsepower and 260 ft/lbs of torque, our second run with the Airaid installed gave us 249 horsepower, and 295 ft/lbs of torque, making for a peak gain of 27 horsepower at the rear wheel, and gains of 34 horsepower, and 55 ft/lbs of torque, throughout the curve. There’s no denying our under the hood appearance has been improved, and our Dyno chart leaves us no doubt that we certainly picked up some solid gains, thanks in part to this intake from Airaid.

Increase horsepower and torque. Airaid Cold Air Intake Systems are computer designed to give your engine maximum air flow, which translates to more horsepower, torque and an increase in fuel efficiency. Airaid intakes are dyno tuned and tested for maximum performance and efficiency.

Superior Filtration. Each cold air intake provides superior air filtration, since it includes an Airaid Premium Filter with SynthaFlow® technology. SynthaFlow® is a synthetic nano-fiber material that traps the smallest dirt particles that ordinary cotton-gauze "performance" filters just can't capture. Airaid Premium Filters, with SynthaFlow® can capture particulates down to 2 microns in size. And best of all Premium Filters are washable and re-usable saving you money.

CARB Certified. Best of all this Airaid Mustang FIPK Air Intake Kit is 50-state smog legal under Carb EO# D-609-5.

Application. This Airaid kit is designed to fit the 1999-2004 4.6 GT Mustang with no computer retuning required. By utilizing state of the art computer-aided designs, Airaid Intake Systems offer unmatched fit, finish, and power!

What should I get ? I wanna get a cold air intake and I'm looking at getting either this one that is listed to add hp and better mpg or I'm also looking at the non-name brand listed $84.99 cold air intake witch is listed to add hp and better throttle response or I might get the chrome BBK cold air intake witch is listed to add hp and better acceleration but I hear they rust after a few years. I've heard this airaid intake adds more hp over the BBK but does it give you less acceleration ? Also this appears to be mounted better and higher up over the other two to prevent sucking up water. Is it worth it to get this ? Will I have more added acceleration with the BBK ? Will the BBK rust after a few years ? Would the $89.99 be just as good ? Will the BBK and or $89.99 be as good as far as MPG ? Witch should I really go with ? what are the facts and differences ?

ProfessorReaper

  • In an effort to effectively answer all of your questions, I will share my own experiences with both the BBK and Airaid kits. If you are looking for the highest quality cold air intake for your 99-04, the Airaid is hands down the first choice. I currently run the Airaid and could not be happier. My first CAI was the chrome BBK, and after three years of use, it did begin to rust. I also take great care of all parts of my vehicle, and polished the BBK several times and it still rusted. As far as performance, I felt a slight pick up in throttle response going from the BBK to the Airaid. I also picked up a very very slight fuel economy boost. Also, the filter Airaid uses in this kit is the best filter you could put on your car. Period. To me, keeping my baby running as long and as efficiently as possible is the most important thing, so the Airaid was an easy choice for me.

So i have a throttle body spacer on my car if i was to put this would i have to cut anything to make it fit?

GermanZ

  • This Airaid MXP Series Cold Air Intake will fit with most spacers however depending on the thickness of the spacer it could push the intake too far forward and cause some slight fitment issues. With so many spacers on the market, it would be difficult to say which units would work and which would not.

I have a functional ram air hood for my 97 cobra svt. They only make a bbk and a C L tube which I dont care about. I know the tube won't fit, its a different design, but will the filter and air box mount to a stock MAF for a 97 Cobra.

  • Unfortunately, we would not be able to guarantee fitment for the filter and air box to be a good fit on the stock MAF on a 1997 mustang cobra.

    AirRaid CAI

    Great Product, purchased this because: 1) Has a shield around the filter that prevents the CAI from taking a lot of air from the hot engine compartment. 2) Shop install advice was, the cheap CAI(s) usually are hard to install because they are not correctly made for a specific car model (ie Mustang GT) 3: Cost to install: $107.91 Very Satisfied

    Great Fit

    Got this as a Christmas gift and put it in today. Great instructions with pictures and very simple to install. One thing I will say, when taking out your old system, dont just rip and throw it out, you will need a few parts. Also, when tightening down the "Hump" boot to the MAF housing, dont push it all the way down, it will interfere with reattaching the MAF sensor. Great intake, not sure about the K&N Box, but the Airaid box has a nice extension that fits into the fender well to grab the air.

    Great OEM look on the car

    I installed this in my 2003 GT in under 2 hours. I found it rather silly about some of the small parts, like AIRAID really couldn't install them themselves. Once in the car I recommend you use the original bolt FORD had in the fender wall as the AIRAID unit is a joke! And MAKE SURE ALL HOSES ARE AND STAY CONNECTED! Car now pulls real strong, even with the stock TB and plenum. Good Buy all around if you don't want go with the pricey JLT unit.

    Great quality product

    Took me and a buddy around 2 hours to put this on late one night. The hardest part is getting the MAF bolted on to the air box, since there is a rubber gasket on either side, which really just takes a second pair of hands. If you have the intake air temp sensor, I HIGHLY recommend using a little lubricant. It's virtually impossible to get the sensor in the grommet without it. I'm very happy with the intake, nice noticeable increase in sound and performance. It's definitely letting my baby breathe a little easier.

    1999 Mustang GT

    I purchased this Airaid CAI to add more HP to my 'stang. Fortunately, this was a great way to make my GT meaner and better airflow. I like this intake, but it was kind of a pain to line up the velocity stack, the nuts, the mass airflow box, and the air intake box. I struggled with it at first, but eventually got it. Also, the weatherstrip was a HUGE pain to try to put on and I couldn't get it so I just left it off. I hope this shouldn't affect me negatively too bad. But other than that, this intake is a GREAT way to add for HP to a GT.

    Best CAI according to AM

    Quality as you can come to expect from Airaid. Very expensive for plastic, clamps and a filter, nevertheless it looks GREAT under the hood. Now I'm proud to open my hood. Noticed a gain. Does about as much as any bolt on. Thanks Shane and everyone else @ AM

    Great Cold Air Intake

    Bought for my 2004 GT. Looks alot better than the stock intake system. I installed it in little over an hour with basic hand tools. Also added the matching Poweraid Throttle body Spacer. I've ran this combo on a few vehicles I've owned. The gas savings pays for the total purchase eventually. Sounds better too!
