Air Filter Media

The creation of aFe’s filter media was the start of it all. Since our inception, we have set out to provide the ultimate air filter. Now, it’s the basis for a wide range of our products and the heart and soul of our industry leading cold air intake systems.

Which Air Filter Media is Right for Me?

aFe’s team of engineers have developed multiple filter media options, offering different benefits to match various vehicle applications and driving conditions.

When choosing an air filter I am most concerned with:

No power or torque improvements can be made without extra air. When it comes to making power, having effective air flow is step number one. With a high-flow deep pleat design and progressive depth-loading layering that protects from dirt, aFe’s filters keep their high air flow as dirt accumulates – providing performance, while still ensuring protection for your engine.
