The HPS Performance 3.5" 304 Stainless Steel Black Intercooler Pipe Kit (Part Number 17-125WB) replaces the cold side plastic charge pipe, located on the passenger side between the intercooler and throttle body. The large 3-1/2 inch diameter mandrel bent stainless steel pipe allows more air to flow into your engine while drastically reducing exhaust gas temperature (EGT). Unlike aluminum charge pipe, HPS Performance 304 stainless steel charge pipe withstand higher pressure and temperature to complement the powerful 6.6L Duramax LML Diesel engine. Stainless steel offers improved corrosion resistance, keeping your engine bay looking clean.

This kit features fluorolined silicone hose designed to resist the damaging effects of oil blow by commonly found in these engines. Also included in the kit are industrial grade stainless steel spring loaded t-bolt clamps and a detailed installation guide to help you get through the project and back on the road quickly.
