Wehrli 20-24 Chevrolet 6.6L L5P Duramax Passenger Side 3.5in Intercooler Pipe - Bengal Red

When you're looking to make sure your 2020-2025 Chevrolet Silverado 2500 HD's 6.6L Duramax engine is breathing as freely as possible, especially if you're running higher boost pressures, this passenger side intercooler pipe from Wehrli Custom Fabrication is a solid choice. It directly replaces the factory two-piece plastic pipe, which can be a weak point and prone to blowing off under increased boost. This upgrade uses a single, larger 3.5-inch diameter pipe made from durable 14-gauge aluminum, designed to handle more air pressure reliably.

Wehrli built this pipe with a CNC machined flange that features a double O-ring seal, ensuring a much better seal than the stock setup. It also comes with an upgraded silicone boot and a black anodized billet aluminum adapter, both designed to withstand higher boost levels and prevent leaks or the boot separating. The pipe incorporates a threaded bung to easily reinstall your factory intake temperature sensor, and it uses T-bolt clamps for a secure fit. This is a direct bolt-on part that doesn't require any other modifications or tuning to install, making it a straightforward way to improve the integrity of your intercooler system.
