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 3/8" to 1/2" 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. This item is built to order. Lead time can be up to 3-6 weeks. All sales are final.
