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

Starting with a 14-gauge aluminum construction, this Wehrli intercooler pipe is built to handle the demands of your 2006-2010 LBZ or LMM Duramax truck. It replaces the factory plastic cold side pipe, which is known to fail under higher boost pressures, with a larger, 3.5-inch diameter pipe designed for improved airflow. This means better efficiency, a more responsive throttle, and quicker turbo spool-up.

Wehrli didn't just make it bigger; they engineered it for a solid seal. The pipe features CNC machined flanges with double O-ring seals, ensuring a tight connection that prevents horsepower-robbing boost leaks. It also comes with new wire clip rings for the slip flanges and uses a heavy-duty silicone hump boot secured by stainless steel t-bolt clamps. This setup is much stronger than the stock components and is finished in a durable gloss black powder coat for a clean look. It fits directly onto stock trucks without needing any other modifications, upgrades, or tuning.

This pipe is a smart upgrade for any 2006-2010 Chevrolet Silverado 2500 HD, 3500 HD, or GMC Sierra 2500 HD, 3500 HD, especially if you're looking to eliminate a common failure point in the factory system. It installs easily with basic hand tools and pairs well with emissions-compliant tuning and drop-in turbochargers for even better performance.
