  • 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.

I love how quick the filters got to my house and how perfectly it fit my bike. I'll be getting my bike's oil filters from you in the future.

Good looking filter, especially like the nut on the end to aid removal, which the Honda filter did not have.

Great product. Exposed oil filters need to be chrome to look good.

I have not had a BAD K&N product yet. They make a quality product at a reasonable price. Their work speaks for itself.
