K&N Oil Filter
  • 1 Inch Nut for Easy Removal
  • Heavy Duty Construction
Colby Harper, Saint Petersburg, Florida
I have a 1999 dodge ram 1500 two wheel drive. It has 140000 on it. Ever since I bought it smokes sometimes when I start it. In general it has always ended up using about a quart of oil in between changes. I read the K&N filter had an anti-drain back valve and a pressure by pass valve. I took a chance and put one on on the last oil change. It has not smoked once. It has not used ANY oil and maintains great pressure even at an idle. Thanks for making one that can give such great results for a very little price increase.

Filter is used on 2007 Charger SRT8 Superbee w/ 0-40 Mobile One synthetic. I used this same upgraded filter on my 2004 Pontiac GTO w/ 5-30 Mobile One. It gives me re-assurance of maximum filteration capability and good service life for my 6k/mile intervals.

Fits my Ford 5610 tractor and the removal nut is the same size as the drain plug.

I do not have any problems with this filter. I will keep using this one and the hp 2004 filter from now on. They give me a good piece of mind to know I have the best filters on the market. I also use the air filters aswell. My son uses these filters also as long as I order them at volume order. Thank you.
