K&N Oil Filter
  • 1 Inch Nut for Easy Removal
  • Heavy Duty Construction
Tory Babcock, Torrington, Wyoming
A little bigger than a FRAM and 3 times as big as a MotorCraft. The only filters for a 5.7 Hemi in my town are Purolator, and I've never tried one. I will use K&N racing filters for my Hemi!
Tim Williams, Weatherly, Pennsylvania
What can I say? It's an oil filter by K&N. Should be a lot easier to replace with bolt on filter.
Malcolm, London, England

Matthew Norman, Oden, Arkansas
Fit 3940 Tractor
Jeffrey King, Marion, Ohio
Went on fine, did not leak. Hard to rate how effective a filter it is but engine still runs on my 30-year-old Kubota Tractor. Service beats driving 40 miles round trip to get filter from dealer. Will purchase again from K&N.
Patricia Reddig, Newark, Ohio

Awesome oil pressure, all of my trucks and Harley have K&N oil and air filters. How many do I have to buy to get a K&N hat?
