Where could i find an intercooler and what size would i buy. What is the little square on the top of the IP. What is IP? How much would an intercooler cost. If you guys haven't noticed i'm new to the diesel life. Where would i get sd 265 nozzles. Are they off of a newer diesel mercedes? Are Bosio nozzles good? Thanks for your help guys. What will these mods do to my engine life?
