I have been using K&N now for many years. I have one on my 1978 KZ 750 B Twin. My 2006 Grand Cherokee Overland (HEMI) has the complete K&N Filter Charger kit and this one on my '08 Heritage Classic. (with a Harley Stage I kit). Tthe only problem so far when I took the filter off to clean at 8,000 miles the outer gasket between the cover and filter had stuck to both and tore. I called to K&N Customer Service looking to find a replacement and after the lady I talked with located what I was talking about on the Parts Breakdown, she took my name and address and said it would be shipped out the next day. That's backing up the Product. Thank you K&N.

I use K&N on all my vehicles and my brand new Heritage Classic is no exception. Instant gratification. The only issue I've HD with any K&N filter is this one and it's not the filter itself, but the gasket/cushion on the outer plate that the cover rides on,when I took it off the clean after 5K miles, it was destroyed. I've already contacted K&N about this and have no doubt they'll fix me up. I'll never use anyone else's filters Great job again, K&N Keep it up
