  • O/E replacement oil filters for most cars, trucks, SUV's, motorcycles, & ATV's
  • 1 inch exposed nut designed for easy oil filter removal
  • Heavy duty construction for extreme conditions
  • Anti-drain back valve (where applicable) eliminates dry starts, prevents oil from draining back into crankcase during engine shutdown
Originally developed for demanding race applications, K&N's Premium Wrench-Off Oil Filter has become a favorite among consumers for its durability and easy removal. Most of our automotive and marine oil filters come with a 1 inch nut welded to the top of the canister so they can be easily wrenched-off with a standard tool. To satisfy the demands of racers, our oil filter has many features over and above the requirements of most vehicles. We use thicker canister walls for extra strength and durability which reduces the risk of damage from loose rocks and debris. The drilled hole on the nut provides for safety wire attachment. Our oil filters also use a resin impregnated cellulose filter media. This allows for higher flow rates while providing outstanding filtration.

K&N HP-2003 Oil Filter Product Reviews

Friday, September 29, 2017 - Part HP-2003
Filter purchased to fit classic Rover 3500v8. Rather 'does what is says on the tin'. The car is a classic cruiser and won't be put through highly stressful driving. I just wanted a filter with a good reputation and this one appears to be a frequently recommended option amongst classic Rover drivers. Paired with Millers Pistoneeze oil. Simple change. One minor criticism is there is too much paint on the 1''' nut so getting a secure spanner-grip is not easy, particularly in a tight space where the spanner head is not perfectly aligned. Would be better if the nut was unpainted or had better defined flames and corners to enable a cleaner grip with the spanner.

I trust this filter to protect my recently rebuilt muscle car engine. The fit and function are exceptional. The built-in end nut fitting makes it a breeze to remove in case the filter is over-tightened on installation.
