    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

The Airaid Poweraid Throttle Body Spacer not only improves the power and performance of your Mustang, but with its unique “Helix Bore” design it also maximizes fuel efficiency saving you money at the gas pump.

            Doesnt work with cold air intakes

            Not only did the directions not tell me that i had to take the studs out of the intake, but then once i got it on i realized that it would not work with my bbk cold air intake so it had to come back off. Do not get if you cannot get studs out of your intake or if you have a cold air intake. 0/5 stars!!!!

            The whistle..

            Besides having to go buy new bolts, install was easy. Whistles when you get going, and when you cut the car off

            Nice product

            It's a nice constructed product but I gave it a 2 star because the size for the throttle body is for a stock throttle body. An they don't offer a spacer like this for a 70mm throttle body on AM.

            poweraid throttle body spacer

            I received the spacer within a week, very simple to install it came very understandable directions it would have been better if there where pictures in color but they still wasnt bad I noticed once my computer recognized it it and some low-end torque it also bumped my mpg to 26 with has made it slot nicer I recommend this product to anyone wanting cheap torque gains

            MUST BUY!

            having my stock throttle body spacer was getting boring so i bought the Airaid throttle body spacer. And not only did i get a much quicker response on the throttle, the nice and loud whistle that will INTIMIDATE OTHERS! gives you the respect. so i highly recommend this!.
