Description

The Wehrli Custom Fab WCF100530 3.5" Cold Side Intercooler Pipe is designed to enhance airflow on 2017-2019 GM 6.6L Duramax L5P engines. It replaces the factory two-piece plastic pipe with a high-flow, 14-gauge aluminum one-piece pipe. The pipe features a CNC machined flange with a double O-ring seal to improve sealing and prevent boost leaks. High-quality silicone boots and stainless-steel t-bolt clamps replace the OEM clip ring design for improved sealing and the ability to hold higher boost pressures. This upgrade aims to increase reliability and eliminate blown factory boots and boost leaks that can rob horsepower. The pipe is compatible with stock trucks and does not require any additional modifications, upgrades, or tuning for installation. It also incorporates a threaded bung for reinstalling the factory intake temperature sensor. The intercooler pipe is available in various powder-coated colors.
