I have K&N air filters in all of my vehicles. Just bought a GMC Sierra 2500 hHD. Put the K&N in before the odometer turned 1000 miles. The filters are just that good.
Barbara Leighton, Florida
These filters are excellent quality and fit. I bought this filter a while back for my Toyota to see how well it worked. I was very pleased, and went ahead and purchased this one for my pick-up. I would highly recommend this filter, and K&N has been an excellent company to deal with. Order was processed and shipped immediately.
