Anyone have results from installing this air filter on 2008 6.4l.? Also, will void the warranty?

I wouldn't run a K&N on a diesel or any other vehicle PERIOD. Go with an AFE, Banks, or S&B. The warranty issue just depends on your dealer.

^^^ What Cobb said. If your going to put an intake on your truck don't put a K&N on it. AFE is loud and works great. S&B is quiet and works great. Can't go wrong with either.

if you are doing an intake. but honestly i think an intake on a stock truck is pointless. jmo

Wichester33 is right. If you don't put a delete pipe and tuner on the truck, it will be pointless. They really don't provide for any gain on a stock truck. I always assume people are doing deletes on here lol. If you are going to do one on a stock truck then go S&B, they seem to be the only one that does not throw a code.

Thanks to all of you for the responses concerning k & n air filter. Due to yall's opinions, I'm gonna hold off on installing any type of new intake for now. I have added the Bully triple dog E3 & it seems to have improved my mpg by about 4 - & it hasn't affected the codes so far.

Hmmmm, 4 mpg increase with a DPF....

Is that hand calculated or by the dash gauge/lie-o-meter?

[DDRN]

Not a DPF. Installed a Bully Triple Dog E3 chip. From gauge I was averaging 13.2 mpg & now with chip am averaging around 17.0.

You have a DPF is what I was saying, unless you have a DPF delete pipe, DPF-R module and the Bully Dog tuner. The dash lies man. I garuntee that if you hand calculated a 300 mile trip you would not see the 17.0 mpg you think you have. It would be closer to the 13.2, probably lower.
