I have a 2011 6.7 and was wondering which is the best aftermarket cold air intake for it?? Which ones are out and how are they??
Also I have been hearing that the stock turbo on the 6.7 is no good and that it will not make lot of aftermarket power??
Anyone have any comment on this??
Here we go again -AFE stage II or the S&B are the best intakes.
The stock turbo is just fine up to a certain HP. Then it runs out of air .
And those of you who are so paranoid about voiding your little warrantee , an intake won't do that. And most cases neither will a tune. This is why you go with a respected company like H&S and KEM who have done tonnes of research and testing. I trust them so I don't worry. If you don't , then leave your truck at 400hp. I love having my 25.5K/lb , 42 foot triple axle toy hauler or my 44 foot gooseneck flat deck with 20 + round bails on and cruising in 6th at 70-80 mph like its nothing. Power is good!! The 6.7 has hardcore safety nets built in place to protect itself, from the dual cooling systems to the oil system ( piston cooling), 6 bolts per cylinder etc. in time we will see it pump out big numbers, bigger than I'm seeing now
