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:
Performance Convenience Longevity Protection
NOT ALL AIR FILTERS ARE CREATED EQUAL
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.

Pro 5r® oiled air filter — maximum performance
The Pro 5R is our most performance-oriented media available, outperforming virtually all other cotton gauze media on the market today. It provides your engine with the largest amount of high-flowing air, usually resulting in the highest horsepower and torque gains out of all aFe’s filter media options.
98.6% Filtration Efficiency

Pro Dry S® oil-free air filter — maximum convenience
Comprised of multiple layers of synthetic media, the Pro DRY S offers excellent filtration efficiency and protection for street and light off-road driving conditions. Requiring no oils, it’s our easiest to maintain performance air filter.
99.2% Filtration Efficiency


Pro 10r® oiled air filter — maximum longevity
Only available for select diesel truck applications, the Pro 10R’s ten layers of progressive media and its massive filter size make for better filtration and more dust holding capacity. Its large surface area provides much longer life between maintenance intervals.
99.59% Filtration Efficiency

Pro-Guard7® oiled air filter — maximum protection
Our Pro-GUARD 7 media was designed specifically for today’s rigorous off-road and diesel applications. Its patented hybrid design features both cotton gauze media and synthetic media, providing the greatest level of filtration efficiency and unparalleled engine protection and performance.
