I bought a 2007 Duramax 6.6 LBZ
what is the best cold air intake system for fuel economy?
I was looking at the Banks with the super scoop with the 6 gun?
any suggestions.
been told the SB is good too?
Look up the "PPE air intake mod"
Which is basically a how to instructional guide to tear apart your stock airbox to flow enough air for 500+ hp
The stock Donaldson air filter is legit
I have the banks intake with super scoop, yes, I was hell bent on spending my money, but only after EFI, gauges, aa built trans and a turbo upgrade
I rocked the modified stock airbox for a while, can't say I noticed a difference between the two...but I wanna say I can tell when the scoop is off the banks intake...probably placebo effect
As far as MPG is concerned, getting EFI and a turbo back exhaust system will net you the best gains as long as your driving for it. An Intake is more eye candy than anything else, and you gotta be real careful about the filter you get, they're not all better than stock, in fact very few are
I will be putting a dry sock around my filter this year to try and further eliminate micro contaminants from the intake tract, the last time I had the turbo intake horn off there was a very slight and very fine layer of dust in there I was not happy to see
