Justin from, we're here with Chris Thompson from Airaid. He stopped by the shop to tell us a little more about these great Airaid products. We're very familiar with Airaid; we use them on our project cars with great success. Chris, what can you tell us about Airaid that makes it so unique? "Everything we do is digitally designed. It's engineered to fit, it's engineered to work, it's engineered to work without any special tuning. Now, tuning is much, much better. You guys offer a lot of great choices in aftermarket tuning. It'll only enhance the performance of the Mustang. We design our intakes so there's no special gluing required, there's no cutting or hacking of the engine required. If somebody decided to put a stock intake back on, they don't have to go back to Ford to buy another part to put the piece back on. Every intake we do is digitally designed. It's all about the design of the airflow and the linear charge to the throttle body. We use the rotational molding not so much for the heat soaking, but for the shape of the tube we can come up with. By using the rotational molding, it allows us to really give the right shape and form to make sure the product works well." We're very excited—we've got our 2013 Mustang here, probably not even 10 miles on this thing yet, and we already have an Airaid intake on it. Tell us a little more about that. "This is awesome. We're really excited to be here today. This is the first Airaid intake on a 2013 Mustang. We're really excited to be here with you guys. As you can see it fits. We know for sure it fits. We believe we have a hit. We'll do a little bit more testing on it before we release it to the public, but that should happen anytime now." Now, you were telling me earlier, you're working with some legends in the Mustang world. "Well, we're excited about working with Parnelli Jones and his son PJ. Parnelli's been instrumental in helping us come along with the Boss 302 intakes we're trying to develop. Nobody knows the heritage of the Boss 302 better than Parnelli Jones. We worked with PJ on the side by side utility vehicles (Razors, Rhinos, and TRX's). We also sponsored him in the past on his endeavors in the American Le Mans Series, which he ran last year." Chris, thank you so much for educating us on your great Airaid products. And as always, you can find those great Airaid products right here at

When you re-install the factory MAF housing it will not fit flush against the new plastic air box with the metal MAF screen in place. Is it normal to leave out the screen when installing and will it cause harm to the MAF.


Helpful (0)
  • When installing the Airaid Cold Air Intake the metal screen would need to be removed from the MAF. This is a common practice and will cause no harm to your engine or MAF sensor.

    Great Intake

    I went with this intake cause I liked the heat shield. It was a pretty simple install that took about an hour, most of that time was simply trying to out one of the provided plugs into the hole *rolls eyes* besides that its great. Adds a nicer sound to my engine I definitely recommend.

    Airaid CAI dry filter

    Installed this in under an hour and look great under the hood. Not much of a performance gain but would still recommend. Looks a lot better then factory intake system and opens the door later for more power with a tune and bigger MAF.

    Before I upgraded to my 2000 GT, I owned a 2002 v6 and installed the SR Cold Air Intake in it. Just installed this Airaid in my GT today, and I'm not too impressed compared to the SR. The fitment was a little frustrating, you will definitely need an extra set of hands for the MAF housing. PCV valve also broke during install, top snapped right off while fitting the CAI and had to run out and buy a new one, so be sure to look out and listen for that. Was looking forward to the sucking and whistling sound that was previously on my v6 when I installed the SR Performance Intake, but this CAI is very quiet, which some may like better. Haven't noticed real MPG gains, slightly more get-up-and-go when I press the throttle, but not as big of a gain as I noticed when I installed the SR on my v6. I really like the efficiency of the filter and how it doesn't set in the wheel well versus the SR Intake; if I'd drive through a puddle, my car would sputter and I could almost hear it sucking up water. Overall, an okay product, I'd say you could get something just as good if not better for cheaper, however.

    Looks good, sounds good, fits great!

    I bought this to replace a Spectre CAI that the previous owner installed on my '99 GT. The finish and packaging of all the parts Airaid supplied was impressive, especially the Synthamax filter. Overall, everything goes together according to the directions, but you'll probably spend more than an hour getting the job finished. It helps to have an extra pair of hands when attaching the MAF housing to the velocity stack and airbox - you have to line up two gaskets and four bolts, and this took me a little time. The fit of all the parts was spot on once everything was together. The finished product looks good in the engine compartment, and I especially like the black filter. I can definitely hear the intake when getting on the throttle now. The car is in stock tune, so I'm not sure how the intake will affect mileage, but it looks and sounds 1000 times better than what was on the car before. All in all, time & money well spent.

    Wanted to add more HP to the stang while adding something that looks great under the hood. easy to install but if your adding this to a larger diameter throttle body you may need to pick up a larger hose clamp even though the boot will stretch over either size.

    Added horse power

    Looks great once installed but Airaid's instructions are not very clear. My friend had trouble with his and he had to get some extra parts. But for me we had to do a little modification to get it installed. Also gives your car a more clear growl to it.

    Nice cold air unit

    Installed into my 01 GT. Took about an hour, fit on my 70mm throttle body without any issues. Already had a KandN filter, full bolt-ons and a tune, so I can't say I noticed a big difference in performance. But it looks nice...

    Nice Intake

    I give a rating of 4 stars since the kit I received was missing the large clamp for the filter itself. Had to buy one at a regular hardware store, which they fortunately did carry. It seems like you should not have to go buy more parts to complete the job considering the nearly $250 cost of this CAI. Anyway, the overall fit is pretty good and the intake has a nice stock-like appearance compared to some other models. Be sure to install the filter when the instructions say to; otherwise you won't be able to fit it in the housing. Also, since I have a larger than stock throttle body, I found that I had to put the reducer coupler on the TB as a separate piece because I had to get my hands inside the reducer to stretch it in place (instructions have you install the large end of the reducer on the plastic tube first). I can't speak to any performance gains since this CAI kit was replacing an older fenderwell-style intake. I especially like being able to see the filter under the hood and not having to deal with any future oiling of the filter, and am overall very satisfied with this Airaid CAI.

    Airaid cold air intake

    I purchased this due to my KandN FIPK mounting kit getting stripped out, bought it used a couple years ago. Overall the non oiled filters seem to be nicer and you can still wash them. I noticed the mounting areas for this kit to be better then the KandN. I can't say there was any change in performance but I would recommend this kit over the others any day including the cheap ones sold here and on Ebay.
