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

This kit gives you a 3.5-inch high-flow passenger side intercooler pipe, designed to replace the weaker factory plastic piece on your 2006-2010 Chevrolet Silverado 2500/3500 HD or GMC Sierra 2500/3500 HD with the 6.6L LBZ or LMM Duramax engine. It's built from 14-gauge aluminum and finished in a WCFab Grey powder coat, offering a solid upgrade for trucks that see a lot of work or higher performance demands.

The factory intercooler pipe is a known weak point that can fail under higher boost pressures, leading to boost leaks and robbing your engine of power. This Wehrli pipe addresses that by using CNC machined flanges with double O-ring seals for a much better seal, along with an upgraded silicone hump boot and stainless steel t-bolt clamps. These components are built to handle more boost, helping to prevent blown boots and leaks, which means more reliable performance. It's designed to fit stock trucks without needing any other modifications, upgrades, or special tuning, making installation straightforward with basic hand tools.

This pipe improves airflow between the turbo and the engine, which can lead to better throttle response and quicker turbo spool-up. While it works well on a stock truck, it pairs especially well with emissions-compliant tuning and drop-in turbochargers if you're looking to maximize performance gains.
