Did you ever wonder how some of those high-flow performance filters get such great flow rates? Unfortunately, some of them use inferior filtration materials. Sure, you get more air through the filter, but you also get more dirt in your engine. The folks at Airaid air filter don't think that's the right way to do things. Each Airaid air filter is designed to flow tons of air, but to also capture up to six times the amount of particulate matter as the competition way down at .5 microns. Airaid air filters catch the small stuff, since they know if they have that covered, they'll stop the bigger stuff with no sweat. How do Airaid air filters work so well? The engineers at Airaid air filters designed a five-layer gauze filter system. You end up with four layers of cotton in a performance Airaid air filter, just like most others. But then each Airaid air filter adds another layer of synthetic material. Yeah, it took some engineering to make it flow as well as the competition, but Airaid air filters decided that the extra protection was worth the effort. Then, each Airaid air filter finishes up with a stainless-steel mesh for support and corrosion resistance. And unlike some performance air filters, Airaid air filters are made for tons of different cars, trucks, vans, and SUVs, so you should have no trouble finding an Airaid filter for your ride. We stock all the different Airaid air filter applications, and you always get our great low prices and fast shipping.
