2007-2008 Jeep Grand Cherokee CRD intercooler upgrade kit. This kit is to replace the restrictive factory intercooler with a 3" intercooler core that flows 33% more than stock. Made from aluminum mandrel bent tubing, custom CNC adapters, stainless steel hardware. Bolts in to the stock location, does require some clearance on the bumper support. This kit improves MPG, reduces EGT's and reduces turbo spool up. The turbo resonator is a great addition to this kit as it helps reduce restrictions in the intake system and remove the leak prone stock resonator. Add the turbo resonator to your order and save. There are two versions of Turbo Resonators in the Jeep WK CRD's, almost all come with the Jeep Version, a very few late 08 models come with the Mercedes Version. Please check which version you have. You can see pictures of each resonator delete on our website.
