Cold air intake

Does anyone recommend a K&N filter or cold air intake for a diesel? Any pics or suggestions would be helpful.

CAI sure, K&N.. no If its NA more or less just make sure the factory CAI tube is hooked up and getting air from the grille. If turbo then youre pretty much stuck with a K&N type filter of some sort. Im running a Spectre cone filter on mine. Your other option is the 6637 mod

i wouldnt recomend a K&N unless you want to sand your engine away. Check out the one below.

I have stock intake with the opening over the engine. round paper filter. Looking to upgrade. Does this help performance as it does on normally aspirated motors?

Basically what you really want to do is NOT get the air from inside the engine compartment. So a cowl like F250 or from the grille like it was stock. Anywhere there is high pressure would be a good place (cowl / grille) I moved both my batteries to one side, built a air box / dam where the one battery used to be and stuck my cone filter there. Made a very noticable difference vs. the filter just sitting in the engine compartment.

Any advice / pics / referrals to other threads would be greatly appreciated.
