Others build and ship without testing. Not Banks. Our Ram-Air Intakes start out as CAD software prototypes and are put through flow simulations. The design is refined until the simulation shows optimal performance. Then a hardware prototype is made and the design is validated on a flowbench. After that comes dyno testing and on-vehicle testing. It takes a superior design to pass all those tests!
A filter on a stick is a bad joke. It’s wide-open to hot, power-robbing underhood engine air. Ram-Air houses a giant filter in an enclosed cold-air box, which inhales cool, dense outside air—more than Banks’ competitors and up to 35% more than stock—for more power (up to +39 hp/+69 lb-ft , with tuner). More mileage, lower EGTs and less smoke, too. And it’s designed to not cause fault or error codes.
Banks Ram-Air is the only aftermarket intake with bellows. This accommodates engine movement and prevents component damage for longer service life.

One of the most commonly asked questions in our service center is, “How do I clean my air filter?” In this tutorial, we explain the differences between oiled and dry filters, as well as how to clean and re-oil them. We’ve even created a free re-oiling calculator so you know precisely how much oil to use. You'll come across people online complaining about oil filters caking up their MAF sensor located in their air intake tube. This occurs only when filters are improperly oiled. In this video, we’ll show you the right way to do it so this doesn't occur. If properly cared for, your Ram-Air filter element should last years and years.
