Forgetting to check the condition of your air filter can have a dramatic effect on vehicle performance and fuel economy. If you have not checked the condition of your performance air filter during the last few oil changes, it might be time to take a look and clean it. It could make all the difference during your next dyno session. Consisting of specially formulated cleaning chemical and oil, our filter cleaning kits are perfect for the proper maintenance of your filter. Depending on your location, we recommend you inspect your filter during every oil change and servicing it every 10,000 to 15,000 miles for maximum performance and protection. For use with COBB SF Intake air filters.
