  • Heavy Duty Construction
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.
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.

As always a great product.

Excellent filters! I won't buy anything else, good value for money and quick delivery.

I buy K&N because of the quality of their products. Buying a cheap quality oil filter at a auto store just doesn't make sense when you consider the investment you're protecting.
