Customer Feedback

What can I say. K&N Rocks! I've installed K&N on everything from my BMW M3 to my Jeep Wrangler. Why not my new BMW F800 GS Adventure?

The KN-164 BMW oil filter with built-in wrenching lug is a great product and surpasses the OEM equivalent based on quality and ease of use. I would highly recommend this product to BMW R1200 GS/GSA owners.

The K&N website is very easy to navigate. I have K&N filters in every motor I can. I feel the filters not only enhance the performance; the filters are also a good environmental product. I am not disposing of used filters. I have a 1998 BMW R1100 RT with over 130,000 miles and a 2004 Toyota Camry with over 230,000 miles that have K&N filters in them. Everytime I buy a different motorcycle or car; a K&N filter is installed if a K&N filter is available. I was glad to see you now offer cabin filters.
