[QUOTE="powerlifter405, post: 1486721, member: 2044"] Funny you mention that. When I had my 6.4 I called AFE and spoke to a tech and gave him the low down on my situation. [B]AFE [/B]flat out said, stick w/ your factory Donaldson and factory intake as it will flow more than enough air for the 6.4 twins even w/ maxed out fuel. The issues is not how much air it could flow but that the twins are the limiting factor. He said for just a tuner on factory turbos on a DD anything besides the Donaldson is not needed. [/QUOTE]
