  • O/E replacement oil filters for most cars, trucks, SUV's, motorcycles, & ATV's
  • 17 mm exposed nut designed for easy oil filter removal
  • Heavy-duty, chrome-plated canister handles extreme conditions
  • Anti-drain back valve (where applicable) eliminates dry starts, prevents oil from draining back into crankcase during engine shutdown
K&N powersports chrome canister oil filters contain a modern synthetic filter media, designed for ultimate flow with less pressure drop, yet engineered for outstanding filtration. K&N powersports 'spin-on' oil filters feature a heavy-duty, chrome-plated metal can. Most of these have a 17 mm nut affixed onto the end that allows for easy removal. The 17 mm nut is crossed-drilled so racers can safety wire the filter to their bike.

Aside from superior filtering, the chrome body enhances the look of my bike, and the 17 mil nut aids in easy removal.

Have been using this filter on my Valkyrie for years. The bolt on the end makes it easy to remove at the end of the season. Compared to the alternatives, it has a nice chrome finish without putting an extra cover on the stock filter.
