Wehrli 20-24 Chevrolet 6.6L L5P Duramax Passenger Side 3.5in Intercooler Pipe - Bronze Chrome

Starting with a 3.5-inch diameter, this one-piece aluminum intercooler pipe from Wehrli Custom Fabrication is built to handle more boost than the stock plastic setup on your 2020-2025 Chevrolet Silverado HD or GMC Sierra HD with the 6.6L L5P Duramax engine. The factory two-piece pipe is a common failure point, especially when you start running higher boost pressures, leading to leaks and reduced performance. This pipe directly replaces that weak link with a solid aluminum construction.

Wehrli uses 14-gauge aluminum for this pipe, which is a strong material that resists corrosion and holds its shape under pressure. The flange is CNC machined with a double O-ring seal, a significant upgrade over the factory seal, ensuring a tight fit that won't leak boost. It also incorporates a threaded bung to easily reinstall your OEM intake temperature sensor, and includes a new intercooler outlet retaining clip. The kit comes with a high-quality silicone boot and black anodized billet aluminum adapter, along with stainless steel T-bolt clamps, all designed to withstand higher boost pressures and prevent the common issues of blown boots and boost leaks found in stock setups. This is a direct bolt-on part that requires no additional modifications or tuning to install, and it features a durable bronze chrome powder coat finish.

This pipe is designed to work with stock trucks, meaning you don't need to change anything else on your vehicle for it to fit and function correctly. It's a straightforward way to improve the reliability of your intercooler system.
