Note: We recommend that you visually inspect your Green High Performance Air Filter at every oil change. As a general rule, a Green High Performance Air Filter should be cleaned at every 30,000 miles. However, this interval can be greatly influenced by your environment and driving conditions. In dusty areas, you may need to clean the filter more often.
