K&N SU-8009 Air Filter Product Reviews

The filter is well made and fit my air box perfectly. The ability to clean and oil the filter for continued use is a positive factor on purchase.

After all I have read, and input from several motorcycle mechanics, I purchased this filter. It has been doing a great job and I noticed slight increase in power as well. Have not had the chance to clean and reuse it yet but expect it to work great.

Although expensive, it works out at about twice the price of normal, so not that bad. The bike does run better, wish I had done this at the start. Bike M800 Intruder 2012.

Installed this filter on my Boulevard C50T and felt the difference immediately. You do have to use the OEM components and snorkel from your original, but it didn't take long to figure it out. Thanks K&N.
