AEM DryFlow Air Filter - 05+ LGT, 08+ WRX & STI

Here in the Pacific Northwest cold air intake systems can be a dangerous proposition. Deep puddles and torrential rain can cause serious damage to an engine if allowed into the intake system of a car. Now there is a better solution, the AEM drop-in Dryflow® air filter. This filter replaces the stock restrictive paper filter allowing more air into your engine without the added risk of a cold-air intake system.

Oil-Free Performance Air Filter
AEM Dryflow® air filters do not use oil so there is no chance of over-oiling your filter which takes the guesswork out of servicing. AEM Dryflow air filters have low restriction while providing great engine protection. AEM's air filter design results in a performance air filter capable of increasing horsepower and torque and so much more!

Easy to Clean
AEM Dryflow® replacement air filters can be used for up to 50,000 miles before cleaning is needed depending on driving conditions. AEM Dryflow air filters on our air intakes can be used for up to 100,000 miles before cleaning is necessary depending on driving conditions. We recommend you check your Dryflow air filter periodically and when it does get dirty don't worry because cleaning is a breeze. Our synthetic air filter cleaner loosens and dissolves filter dirt and grime so it can be rinsed away with water.

Replacement Dryflow Air Filters
Developed in collaboration with K&N, the inventor of high-flow air filters, we adopted some of the best elements of cotton air filters into a new generation Dryflow Air Filter. This new three-dimensional filtering medium is red in color. It uses both depth loading and structural screen wire to enhance airflow capabilities. We use this material with structural screen in our OEM replacement air filters. AEM Dryflow air filters are engineered to enhance your engine's performance. They come with AEM's Lifetime Limited Warranty.
