      Review & Installation Video

      Hey everyone, Justin from 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.

        Good Air Intake

        I just installed this intake on my 5 speed '02 Mustang GT convertible. I've owned the car since new, and it was bone stock until this year. I installed a Borla S-Type cat-back exhaust, 18" rims, and 3.73 gears a couple of days before the intake and noticed a bit of a drone. I installed this intake with not much in the way of expectations, but two things happened, the car definitely seemed to breathe better, especially up top, but the drone in the exhaust went away!!! The install was pretty straightforward and most of the parts seem of high quality except the gasket around the air box, I am not convinced of it's longtime durability or even if it will stay in place. So far I'm happy, and I'm sure when my SCT Tuner arrives, I'll have the benefit of whatever small gains tied together with the speedo adjustment and I'll start looking for my next upgrade.

        Good purchase

        This was a good purchase. I haven’t noticed much change in hp, but I definitely get better gas mileage compared to stock and it does give me a little more get up and go; just nothing to really brag about. I’m sure with other mods i would definitely feel the difference.

        AirRaid cold air intake

        Had this on my 04 Mustang GT for a few weeks now and still love it. Immediately noticed an increase in acceleration and even gas mileage. Overall the car just feels better since putting this on, and honestly you probably put it on in an hour or 2 if you have the right tools and good help.

        Airaid MXP

        A lot better than the last system I had. Went on in just about an hour, fits like a glove and looks great. I bought this system mainly because of the cold air box. Once the rubber seal is installed around the box, the filter gets most of it's air from the fender area where it was originally intended.

        Great CAI

        Fitment is great and I could feel a little increase in the throttle. Be careful screwing the housing for the maf sensor. I cracked mine going to tight.

        Not impressed

        After putting my GT 2004 Mustang on the dyno, for the second time, it showed a gain of 2hp and torque. So for the money I'm not impressed.

      5 Top Rated Questions

      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 ?

      • 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.

      Does this intake come with an IAT sensor hole? Does this intake come with the IAT sensor hole that the 2000 mustang gt have?

      • Yes.

      Will this CAI increase HP and TQ all on its own without the Bama Tuner ? Or will it definitely need a Bama Tuner to gain real results ?

      • This tuner will still gain you HP and TQ numbers but to achievethe most out of the intake a tuner will be needed.

      Would a 90mm MAF bolt up to this or would i need to get some sort of adapter

      • A larger coulper would be required for a 90mm throttle body.
