The 3.5" High Flow Passenger Side Intercooler Pipe for 2020 and Newer L5P Duramax replaces the factory plastic two piece pipe with a high flow, 14 ga. aluminum one piece 3.5" pipe. This part uses a CNC machined flange with a double o-ring seal and an upgraded silicone boot with black anodized billet aluminum adapter in order to withstand higher boost pressures than the factory components to increase reliability and eliminate blown factory boots and boost leaks. This pipe is compatible with stock trucks requiring no additional modifications, upgrades, or tuning for installation.
