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

The cleaning interval depends on your driving conditions. K&N recommends inspecting the filter every 25,000 miles and cleaning it when you see a buildup of dirt and debris. Off-road conditions require more frequent cleaning.

What do I need to clean and re-oil my K&N air filter?

You'll need a K&N air filter cleaning kit, which includes both the cleaner and the oil. Follow the instructions in the kit. Be sure to let the filter dry completely before re-oiling.

Does this filter come pre-oiled?

Yes, this K&N air filter comes pre-oiled and ready to install. You don't need to oil it before the first use. Just clamp it on and go.
