CARB Compliance / Exemption Warning: If you live in California and your application for this product is not CARB Compliant / Exempt, then you cannot purchase it for public highway or street use (in that case it could only be used for formally sanctioned race use on a racing vehicle that may never be used on a public highway or street). If your application is not CARB Compliant / Exempt and you're shipping to California, our system will let you know on the final checkout page.

If you live outside the United States and Canada, we cannot ship this product to you. This is because we are a U.S. AEM Authorized Dealer, and we can only sell to the U.S. and Canada.

An AEM Dryflow synthetic air filter eliminates any warranty concerns because there is no chance of oil traveling up the inlet path and damaging the Mass AirFlow (MAF) sensor. AEM's Dryflow filter also features the best fine dust/dirt filtration abilities in the industry, so you know your engine will be protected just as well or better as compared to your OEM filter.

Fitment Notes: Please measure the diameter (where the filter is) of your current intake system before selecting an application. These filters will work with any brand intake system that uses a similar sized filter. Please make sure the inlet size matches the diameter of your current intake system.

Cleaning Notes: We suggest this air filter should be replaced every 15 to 20 thousand miles, depending on your conditions. Although a cleaning kit is available, we recommend just replacing the filter when it comes time for a cleaning. Even though this method costs a bit more, it ensures you get the best performance out of the filter (oftentimes customers will not use the cleaning kits correctly which can results in decreased performance and filtration abilities, and over-oiling an oiled filter can cause MAF sensor clogging).
