      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

        Replacement filter

        After having cleaned and oiled the old filter so many times, it was time for a new one. This Airaid filter replacement came preoiled with a new clamp, very simple for anyone to replace.

        Air raid filter

        Works great and looks even better. I recommend this product. I can see the air being sucked by it when I press the throttle. It doesn't even take long to install,it took me approximately 5 mins.

        keep it cool

        I like this intake setup because it allows more airflow plus I don't ever have to replace the filter just clean it once a year which only takes about 10 minutes and it saves a lot of money and gas or should I sayyou get better mileage with this air filter I would buy another one

      Hey I wanted to know do u have to oil this filter?

      • This Airaid Cold Air Intake Replacement Filter, the Synthaflow, comes pre-oiled and will not need to be oiled prior to installation. Since the filter is reusable, you will need to re-oil the filter if you reuse the filter after cleaning.
