How often should I clean this filter?

K&N recommends cleaning and re-oiling your filter every 50,000 miles for normal highway use. If you drive in dusty conditions, you may need to clean it more often. Use a K&N filter cleaning kit to maintain the filter's performance.

What is the flange length on this filter?

The flange is the part that clamps onto your intake pipe. This K&N RP-4660 filter has a flange length of 5/8 inch, giving you enough surface to get a good, tight seal with a hose clamp.

Does this filter come pre-oiled?

Yes, this K&N air filter comes pre-oiled and ready to install. The oil is what traps the dirt, so it's important to re-oil the filter after cleaning. Use a K&N filter cleaning kit, which includes both the cleaner and the oil.
