I wonder if I take the bell off a tuba and put it on the front of my truck and run it into the airbox if that would help my MPG's??

Just make sure you oil the tuba flange first...the road salt will destroy that thing in a few days and it would look like the bell off a clarinet. Try duals. Better yet, run one through the hood and have an intake/velocity stack.

I'm not accepting you get that kind of MPG increase just by changing from a 6.7 to a 5.9 filter.

What about all of the folks who have put the very high flow after market filters on? They all consistently report an increase in turbo and EB sound levels, but little or no difference in MPG and little difference in performance other than possible crisper throttle response.

3800 miles later - truck has not blown up and mileage is still WAY better than it was.

Laugh all you want......then try it.

no one expects it to blow up.

I'll run a couple tanks with a 5.9 filter if I ever get my truck back.

I agree, way too quick to say it isnt true! we are all looking for ways to get better fuel milage out of these 6.7s, so lets work together to make the trucks better. Milage per gallon on these trucks is going to differ because of the way we drive,terrian ,4.10 vs 373, auto vs stick ect.... just my 2 cents worth!!

5.9 vs 6.7 filter

My opinion. They put a different filter in the 6.7's to trap more of the dirt/etc that gets sucked in. In severe conditions the 5.9 stock air filter was way to liberal in stopping dirt. A friend of mine (cotton farmer) had Dodge warranty his dusted 04 5.9 with a little less than 100k miles. He used Wix air filters and changed them every 5k miles, had proof of purchase for the filters and Dodge covered it.

Hey,I just traded out of a 2001 GMC 8.1 voretc w/ allison and 4.10 rear..... I think the mileage is great compared to 8 and 9 not pulling and 5 and 6 pulling a 40' toyhauler. I get about 15 to 16 mpg not pulling,,,,,, Looking forward to putting the trailer behind it to see what I will get.....
