I got poor MPG results when I switched to the Banks Exhaust and cool air Intake. I was told by the sales geek that the mileage would improve esp. since it was a diesel. Not so. I went from 21 on the Highway down to 18.5. The power does seem better, but I was specifically after more mpg's. Buyer beware is the lesson for me. It wasn't cheap either. Just had to vent!

 

in my opinion the only thing Banks has that is good is the intercooler and the Sidewinder intake manifold. its funny how a guy who has a awesome Cummins powered Dakota and stupid fast Duramax powered S10 makes such crappy performance products.

 

You prob so no gain to to your heavier foot after feeling any increase in performance. I have had banks tunes and the intake. The tunes aren't that great but I couldn't say the intake was any better or worse than any other. Granite I know longer have any of their products
