How often should I clean and re-oil my K&N air filter?

The cleaning interval depends on your driving conditions. K&N recommends cleaning the filter when dirt accumulates to the point where the wire screen is no longer visible. In normal paved-road conditions, this might be every 50,000 miles, but dusty conditions require more frequent cleaning.

What is the warranty on this K&N air filter?

This K&N air filter is backed by K&N's 10-Year/Million Mile Limited Warranty. This means K&N warrants that the filter will perform properly for up to 10 years or 1 million miles, provided it is properly installed and maintained.

Do I need to oil this filter before installing it?

This filter comes pre-oiled from the factory and is ready to install. Over-oiling can damage your mass airflow sensor, so don't add more oil unless you have a cleaning kit and are re-oiling it after washing.
