This is one of the reasons why 6.4 Hemi V8s come with an oil-to-water oil cooler. Oil jets, or squirters, spray engine oil on the bottom of each piston to remove combustion heat. The 6.4 Hemi engine block features piston cooling jets. Like in the 345 Hemi, the main bearing caps are cross-bolted. The new 392 HEMI comes with a forged steel crankshaft. However, these two engines don't share neither bore diameter nor stroke size. but all programers leave a trace on your computer.Like the 5.7 Hemi, the 6.4-liter version is built around a 90-degree, cast-iron cylinder block with a deep-skirt design. If you must change something, I would use the Edge Evolution with the in cab display (very nice unit). the intake is about the only thing that will not trip a code or void a warranty. but you are going to have warrenty issues with your truck and do not need the problems of a dealership cause you changed parts on your truck. I know you will get 100 diferent sides of this and of course this is just mine. But again that filter will not let you change your exhaust from the turbo back only from the filter back and then your just adding noise, not much performance. On the good side of adding a 4" exhaust you can lower your EGT's and that is important when towing. adding a large exhause can make your engine run cooler and you will loose fuel economy. I have even talked to guys that have only changed their intake and exhaust thinking they would just get better fuel economy, but in the long run lost it, diesels run better when they are hot. If you decide to tune it, your tuner can hurt this filter and plug it up if it does not burn 100% clean. Your truck has a DPF (diesel particulate filter) on it and everything I have read about these, they are nothing but a pain in the arse. I know it was already said, but I would not chip or do anything aftermarket to your truck just yet. ![]()
