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.


  • 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)

Its a K&N filter
A brand that, if you don't know, you should know. This is the first K&N oil filter i've purchased. One footnote: The black paint flakes off over time. Not sure its due to extreme temperature swings but it does it. Does affect the performance but an aesthetic eyesore. Removal of the filter is a breeze thanks to the bolt in the middle. You dont need a oil filter wrench to remove.

The hex just makes really good sense. Plus K & N makes well respected filters.

I've used K&N for years in my cars so when I got my bike I figured it was only common sense to keep with the company that's done me right so far.

Besides the easy off nut for removing this filter, how does the quality of this filter stack up against S&S filters made for Harley Davidson? I want only the best for my 2005 Sportster XL1200C because, that's what keeps me rolling.
A shopper on Apr 17, 2016
BEST ANSWER: Hey are the best filters I've been using them on Harleys for yrs. I highly recommend this for your 05 sporster. I own one as well
Will this fit a 2006 ultra classic?
