K&N filters are designed for use with synthetic oils.
Meets QS9000 specs.
Made with synthetic-blend filter media for better filtering efficiency & protection.
I have been using K&N oil filters on all my atv's for the past 6 years now and we have never had an engine failure due to a malfunctioned oil filter.
These oil filters do just that, they trap contaminants before they get the critical parts of your engine.
These filters work, and work well to protect your engine, and I highly recommend any K&N product for your vehicle.
Note: These filters do their job, but will not if you don't change your oil on a regular schedule. One thing we always do is change our oil, and clean our air filters after riding in the sand or very dusty trails.
