I ordered a new filter. Got a great price saved lots with ordering direct & the shipping was fast. K&N makes the best filters in my opinion & have a great warranty too.

This replacement filter for my Harley-Davidson motorcycle was easy to install. I am still waiting to take the motorcycle for a ride but I am confident that it will be an improvement. Delivery was fast, free, and ahead of schedule.

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.
