Regarding all of the custom air intake systems... Will they improve fuel mileage? my instinct says no. Also what is the purpose of getting one installed. Advantages / Disadvantages ect.

the better your system breathes the cleaner and more efficient you will run. i have an airaid system, i dont think i got any better milage, but it feels like the turbo spools up faster and i have better throttle response.

Thanks Chuck. Think I'll hold off for a while on that.

I installed the Air Aid and their MIT Modular intake tube. I got 1.5 MPG better doing the exact same in-city driving on the first tank. Combined I spent about $250.00. That may seem like a lot but 1.5 more miles for every gallon over the life of the truck is seems like a smart move. I also noticed quicker throttle response and turbo spool. The best thing is the sound of the turbo whining.

I've got a prototype of SP Diesel's intake kit on my 600 and the change in throttle reponse is definitley noticeable. Not sure on the mileage difference, because I did not have the truck long at all before the intake went on.

In theory if you drive the same way, your mileage should increase slightly with a freer flowing intake.

thanks guys for the input!!!

With my intake system, I did notice about .5 to 1mpg better in town, but nothing going down the highway at 70mph. It did lower my EGT's at cruising speeds though.

I installed a MAC cold air system on mine and it gave me a much quicker responce on the trottle, and I've gotten a 1.2 mile per increase, that being said the turbo whine is fairly loud so I installed a TAG in front of it and that made it a lot quiter ! So the cost, 189 for the air system and 130 for the TAG ! Then I installed a Magna Flow s/s exhaust and I now get 23 or better on the road and 22 in the town and freeway driving!

abb, where did you buy you MAC cold air system. That seems like a good price.
