Frequently Asked Questions

Is this a replacement element or a complete intake system?

This is the replacement filter element only. It fits K&N Aircharger intake systems already installed on your Harley.

How often should I service this element?

Inspect every oil change and clean when visibly dirty using K&N's filter service kit — typically every 50,000 miles in normal riding.

Can I use this in a stock airbox?

No — this element is designed specifically for K&N Aircharger intake kits. It will not fit stock Harley air cleaners.
