Wehrli 06-10 Chevrolet 6.6L LBZ/LMM Duramax Passenger Side 3.5in Intercooler Pipe - Gun Metal

This kit gives you a 3.5-inch high-flow passenger side intercooler pipe, fabricated from 14-gauge aluminum, designed to replace the factory plastic pipe on 2006-2010 Chevrolet and GMC 6.6L Duramax LBZ and LMM trucks. It comes with CNC machined flanges featuring double o-ring seals for a solid connection, new wire clip rings for the slip flanges, and an upgraded silicone hump boot with stainless steel t-bolt clamps. This setup is built to handle higher boost pressures, helping to prevent the common issues of blown factory boots and boost leaks that rob your engine of power.

The larger diameter pipe and improved sealing work together to increase airflow between the turbo and the engine. This can lead to better throttle response, quicker turbo spool-up, and overall improved efficiency. It’s designed as a direct bolt-on upgrade that fits stock trucks without needing any other modifications, upgrades, or special tuning. The aluminum construction is strong and lightweight, and the gun metal powder coat finish adds a nice touch to your engine bay while resisting corrosion.

Installation is straightforward with basic hand tools, making it an accessible upgrade for many Duramax owners. While it works great on stock trucks, it pairs well with emissions-compliant tuning and drop-in turbochargers if you're looking to maximize performance gains down the road.
