K&N HD-0800 Air Filter Product Reviews

Wednesday, November 8, 2017 - Part HD-0800
This particular air filter is used on my Harley Davidson 2003 FatBoy, the engine of which was upgraded to 103 cubic inches. The filter is part of the Screamin' Eagle air flow kit and provides free breathing for the engine to develop its maximum output. I use K&N air and oil filters on all of my vehicles and have found that they allow optimum performance for the engines.

It's K&N. It's the only option for quality and reliability. K&N filters are the absolute first thing I put on any vehicle I own, be it motorcycle or truck, car or quad, each and everyone gets a K&N. Worth every penny you pay.
