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.

These filters now use Injen's Super-Nano Fiber technology, which is a dry media and requires no oiling. The new filter media captures/holds more dirt and allows better air flow than conventional air filters. Injen Super-Nano Air Filters also improve engine performance and help engines last longer by keeping them cleaner.

Injen designed the first urethane filter with a built in velocity stack for the ultimate in airflow and performance. The Injen Technology Research and Development Team calculates each filters mesh and pleat count for each specific application during the development stages.

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).
