I have a 2009 2500HD 6.0 that I would like to put a cold air intake on. No one seems to make it for this model. My question is, what will fit and what mods need to be done to get it to fit. Preferably K&N.

 

look at the stock air intake...see the resonator box...wonder why its there? If you remove it, the baffling effect it designed to prevent will actually reduce air flow into the engine. if you like jewellery... put on a cai.
