How often should I clean this filter?

K&N recommends cleaning and re-oiling your filter every 50,000 miles for normal highway use. Depending on conditions, more frequent cleaning may be required. Inspect the filter regularly and clean it when you see a buildup of dirt and debris.

What is the flange length on this filter?

The flange is the part of the filter that clamps onto the intake tube. This filter has a 1-inch long flange, giving you plenty of surface area for a secure connection.

Is this filter street legal?
