Gas Mileage

[Denise Spenser]

in general, does anyone know how much horsepower a cold air intake really puts out?? Does it improve gas mileage??

[snackpack]

it improved my mileage. and it depends on what other mods you have done on HP gain and what year. i know the stock airbox can support quite a bit of power.

depending on how you run it... most are about a 12-15 hp gain they claim, i think i got about 7 out of my k&n and somewhere in the neighborhood of about a 1mpg gain....:thumbsup

i'm planning on adding an aem brute force hd intake kit on mine, one of the local diesel mechanics said that the intake would add 1-2 mpg depending on your driving style

S&B Cold Air here...love it, looks awesome too. Throttle response seemed to improve, didnt seem to have a 'lag' in accerlation. overall, i got 1-2 MPG better.
