Excelllent quality.
Kenneth Davidson, Arizona
Like many of you, I have been using K&N filters for a long time, probably over 20 years. I put this one in my Tundra and it sounds awesome, but of course I swiss-cheesed the heck out of the intake box too. These all fit so well, I purchase them for all of my vehicles. These are so easy to clean and oil you don't need to wait until they are all soiled up. I like to grab all 3 of mine and do them, maybe every year or so, then they are good for another year. K&N is so awesome I found they even make one for my Sthil chainsaw that I have my sights set on. I highly recommend these.
