K&N Oil Filters

K&N Oil Filters are designed to satisfy the needs of racers and engine builders as well as the average motorcycle or ATV owner who wants the best oil filter available. K&N Oil Filters feature synthetic medias that trap 99% of harmful contaminants without compromising oil flow rates.

The K&N 'wrench off’ oil filters feature a 17mm nut affixed onto the end that allows for easy installation and removal. The 17mm nut is cross-drilled making it super easy to throw on a safety wire. Its heavy duty canister and base plate protect against punctures while the double-rolled seal and pre-lube gasket ensure a secure seal.

Features:

  • Compatible with conventional, synthetic blend and full synthetic oils
  • High-flow rate synthetic media filter
  • Traps 99% of harmful contaminants
  • Pressure relief valve and anti-drain back valve (where applicable)

It filtered my oil something fierce. From the day I got it in the mail and held it in my hands till the day I laid it to rest in the garbage can, the only thing it wanted to do was filter my oil. I'll never forget that filter. RIP

Great for an easy oil change.
I purchased this oil filter after watching a Revzilla video where Lemmy did an oil filter comparison. I can't say more than it's an oil filter and that I changed my oil shortly after I received it in the mail. I definitely recommend this to all Harley guys who know that changing their oil on the 96 cube and up bikes require the removal of a sensor or a special oil filter wrench to remove the filter. Quality product and of course will always buy from Revzilla!

Best filter! Period!
K&N Oil filters are the only filters I will use on my 2014 ZX6R 636. Will another filter work? Yeah I'm certain it would, however the peace of mind I get from K&N as well as the nut on the head of the filter make them worth their premium price hands down. Spend the extra scratch on high quality oil and filter and take care of your ride!

Will this fit a 2014 Kawasaki Ninja 300 ABS? It says that it will fit a 2013 model but it doesn't specifically say 2014, though I don't think the size of the oil filter changed but I just want to make sure.
