I was getting 15.7mpg empty and 8.8mpg with the truck and trailer. I just cut out the fins in the air box and the last trip I did I got 18.2mpg. The 15.7 mpg was one day before I cut the fins out. The truck has 500 miles on it.

Take the baffle out of the airbox and cut the fins out, I used a rotozip to do this. The air box just pulls right out. Just have to take the hose clamp off. It really works.

I cut the fins out today and put a K&N in place of the factory air filter. I hope this will help the mpg.!

please do your self a favor and install the oem filter again or a AFE,Volant,S&B or a Amsoil filter but anytning but the K&N the reason i say that they allow to much dirt into the turbo housing ruining the bearings and after awhile you will need a new turbo..

thats good to know, but sucks on the other hand! I wish I would have known that and put that $75.00 towards a good filter. thanks for the info

Yeh, take that K&N out as fast as you can or you will trick, ruin, trash your mass air flow sensor, not only do K&N's not filter good, but they deposit oil all over the mass air flow sensor, screwing up your mileage, throwing codes, etc.. The gasoline rodders experienced that pain several years ago. Like the previous thread said, go with oem or the other none oiled filters. If your K&N has already oiled the mass airflow, there is a specific cleaner for getting the oil off of it.
