If your driving a duramax, I'd skip the intake. Many tests show the factory filter is far superior to the aftermarket ones. Dyno #'s show they also don't help until HP gets over 500 or so. I'm still running my stock muffler/exhaust, so there's some more money you can save, unless you like the sound that is.
I am looking to into hauling classic cars. So Iam doing my research. And seeing what you guys have for tips,ideas andwhat performance parts actually work and what does not. I was a diesel wrench for 5 yrs. So I am that wet behind the ears. kelly
If you want just some extra power for towing there is alot of options. You can either get a box and a set of gauges or a box that comes with a digital gauge. I like the van Aaken box the best if you are going to do the analog style gauges. If you want the digital I like the Edge W / Attitude. That would get you a pretty good start :ar15
Banks is just an overpriced name with cheep performance, and as for the intakes there are lots of guy making close to and over 500 rwhp on the stock setup and the oiled filters like a k&n and others will cause you nothing but problems with your maf sensor so the coin can be better spent on something like a boost increaser or gauges, imo!
