PPE Duramax Intercooler
If you drive a Duramax, you may want to consider this intercooler from PPE. It’s designed to be as large and efficient as possible. These intercoolers will lower intake temperatures by up to 120 degrees and flow about 15 percent better than your average stock part, resulting in higher boost pressures. This intercooler will give up to a 200-degree drop in exhaust gas temperatures, and is especially useful if you use your daily driver for high load situations, such as sled pulling, drag racing or towing.
The factory GM intercooler causes a two to three psi turbo boost pressure drop in a completely stock engine because of its small 1,083-cubic-inch internal flow area. Larger PSI drops can be seen with increased turbo boost, causing a loss of power and efficiency. Pressure drop is virtually eliminated with PPE’s larger and more efficient intercooler. MSRP: $1,725.
