Here's my story.

I was pulling a 30 ft fifth wheel with a 97 f-150, that I just sold to upgrade to a new F-250 Diesel. Now that I found out they are terrible on fuel I am puzzled . I am thinking I should wait for the 2009 to see if they get better mpg. This site has really been helping with me with my decision (that I haven't made yet by the way). My father in law on the other hand did by one. He has a 08 F-250 Lariat. He isn't one to make huge upgrades to his truck but he heard changing the air filter could make some difference (even if minor anything will help). My question to you guy's is will it make any difference and if yes which ones are recommended.

Thanks in advance and thumbs up to a great job with this site.

Air intake and Exhaust. Just putting on a cold air intake w/ a different filter, and a better than factory exhaust will help out a lot.

air filter will not make a difference, there are some people on here that have said that it made it worse. I have the airaid intake and it might of given me .2-.5 increase but nothing to brag about. Exhaust won't do anything either I bought the Magnaflow 5" exhaust and that didn't increase my mpg or give it anymore sound, the problem is the DPF filter. I know u said no huge upgrades but to get good mpg your only good option is to remove the DPF and get a tuner. U will c a big difference if u did that. Good luck!!

Welcome to the org.: An intake/exhaust (aft of the dpf) will get you zero to nothing in mpg. But you really don't buy these trucks (diesel) for mpg do you? Isn't it for the torque? If you're towing you're mpg is going to be crap anyway (with a heavy duty truck). You could buy a Tundra/Titan with a skin that could be dented by a feather and a frame that would fold like spaghetti???? Apples to Apples and Oranges to rice.
