is there a gas mileage increase? debating on selling my extended warrantee back and going for the dpf and i hear a nasty rumor a codeless egr delete is right around the corner from s&b. just got their cold air intake ts a tight fit, seems to suck a decent amount of air but i really loved the sound of the voolant i had on my 06 5.9 In all fairness though there was alot more room t work with for the box and the size of the intake in the 5.9
they must grease those 6.7's to get em in there. I had to hire a anorexic to get to a few bolts...lmao
