I don't do oil analysis so I can't comment on what this filter takes out of my vehicle engines ('11 Durango 3.6 & '12 200 3.6) but I do know K&N quality from using 3 cold air kits and 2 drop in's. With the quality and the cheaper than other brands pricing and free shipping, it's very easy to keep coming back for K&N products.

I've purchased many K&N filters, and many from the online store. I've never had a bad experience, or a complaint of any kind, from the service, merchandise, shipping or cost. I will continue buying K&N products, and continue buying them online and from my local stores, cause I have always found them to be the highest quality, and filters are a cheap insurance for extending the life of a motor.
