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

This is the Wehrli Custom Fabrication passenger side intercooler pipe, designed specifically for 2006-2010 Chevrolet and GMC trucks with the 6.6L LBZ and LMM Duramax engines. If you're working on these trucks, you know the factory plastic cold side pipe can be a weak point, prone to cracking or blowing off under higher boost pressures. This part swaps that out for a well-built, larger diameter aluminum pipe that can handle more air and pressure.

Crafted from 14-gauge aluminum, this 3.5-inch pipe is built to last. It features CNC machined flanges with double O-ring seals, which create a much more reliable seal than the stock setup, helping to eliminate those horsepower-robbing boost leaks. It comes with new wire clip rings for the slip flange connections and includes an upgraded HD silicone hump boot along with stainless steel t-bolt clamps. These components are designed to withstand higher boost levels, giving you improved reliability and better throttle response. The best part is, it's a direct bolt-on installation that doesn't require any additional modifications, tuning, or upgrades to work with your stock truck.

This pipe is a solid option for anyone looking to improve the efficiency and reliability of their Duramax's intercooler system. It's finished in a custom WCFab Red powder coat to look good under the hood. While it works great on a stock truck, it pairs well with emissions-compliant tuning and drop-in turbochargers if you plan on making more power down the road.
