My 05 with 120k is loseing 5-6 quarts of oil between 4000 mile oil changes. I have no leaks, I have checked the air to air and it is dry, and there is no blowby. The tubo spins with no play, truck runs great. I cannot figure out where im loseing it!!! Maybe Im loseing it!!LOL. Whatcha think??

Check back and let us know what he finds.. and good luck.

I have also heard bad things about the K&N on a diesel.My question is what about the other brands such as AFE or S&B that use an oiled filter element.Do they have the same issues as K&N?

There is not one single good reason to run anything by the OEM 4" filter on a 3rd gen.

Thats what I am running, always had a sucked up filter indicator with 2 inch filter switched to a 4 inch drop in and it has never budged since.

I read an article on TDR that basically said the Mopar 4" and stock air box was good to 500hp.. They concluded any performance gains made with the K&N style systems we negligible, and you get a shitty filter to boot.

Exactly.
