K&N RC-3690 Universal Clamp-On Air Filter Product Reviews

Monday, August 8, 2016 - Part RC-3690
I have had this product on my 2005 Dodge Ram Daytona Edition for over 110,000 miles and have no complaints. I ordered a new one since I got a little behind on the cleaning, which was entirely my own fault since I live in the country around farms. The new product was easy to find on the K&N site for my vehicle even without knowing the part number. The order was shipped very quick and received within days of original order. Very happy with these filters and will be using them in all my vehicles from now on.

I have been using K&N air and oil filters for the past 5 years. I purchased RC-3690 as a spare to use while cleaning one I have. Truck runs great getting the proper air flow.
