Application: 2006-2007 LLY/LBZ (1150410) Duramax diesel engines

Description: PPE's Duramax intercooler is designed to be as large and efficient as possible while still fitting into a stock GMC or Chevrolet. This intercooler will lower intake temperatures up to 120 degrees, flow about 15% better than stock, and will actually result in higher boost pressures. They also will give up to a 200 degree drop in exhaust gas temperatures, and are especially useful if you are in high load situations such as sled pulling, drag racing, or towing. Bolt-on intercooler.
