How often should I clean and re-oil this filter?

K&N recommends cleaning and re-oiling your filter every 50,000 miles for normal highway use. Depending on your driving conditions, you may need to service it more often. Check the filter regularly for excessive dirt buildup.

What kind of oil should I use to re-oil this filter?

Use only K&N filter oil to re-oil this filter. Other oils may damage the cotton filter media or reduce its filtration efficiency. K&N filter oil is specially formulated to work with the cotton fibers and trap dirt particles.

Does this filter come with a clamp?

This filter is designed to clamp directly onto a 3-inch intake tube. A clamp is not included. You'll need to supply your own clamp to secure the filter to the intake.
