K&N RU-4990 Universal Clamp-On Air Filter Product Reviews

Thursday, May 17, 2018 - Part RU-4990
Unfortunately this filter was not on stock in Europe. I was forced to wait for weeks before it arrived and had to cancel my first order I placed with a distributor, before I replaced the order with an order direct from K&N. That order did also take some time, so Finally received the product. Product itself is perfect, no negative feedback there.

Customer service is excellent. Initially purchased the wrong filter. I bought a 2 1/2 inch filter but needed a 3 inch. Got an exchange with no problems. Thank you K&N.
