Customer Feedback

Quality product, fair price, and quick delivery made this purchase a win win. I love driving a BMW and I love not paying the dealer to change my oil. I will be ordering again.

The filters were easy to install thanks to the included instructions. They work great and seem to have quieted the fan noise a bit. It will be awhile before I use the cleaning kit but I sure do like the top quality of these filters. I am purchasing a new car in June and already have the part numbers for the engine air filter as well as the in cabin filter. I have a 2013 3series BMW and would love to have an in cabin filter for it.

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?
