Wehrli 04.5-05 Chevrolet LLY Duramax Passenger Side 3in Intercooler Pipe - Illusion Blueberry

Wehrli Custom Fabrication is known for making solid parts for Duramax trucks. This passenger side intercooler pipe is a prime example, designed specifically for your 2004.5-2005 LLY Duramax. It replaces the factory's restrictive 2.5-inch pipe with a larger, 3-inch mandrel-bent aluminum pipe, which helps the turbocharger push more air into the engine.

This pipe is made from 14-gauge aluminum and uses upgraded silicone boots with T-bolt clamps. These components are built to handle higher boost pressures than the stock parts, meaning you won't have to worry about blown boots or boost leaks that rob your engine of power. The connection at the intercooler is straight, unlike the angled factory boot, which can improve flow. Plus, it comes in a cool Illusion Blueberry powder coat finish to look good under the hood. It’s designed as a direct bolt-on replacement that works with your stock Y-bridge and crossover pipe, so no extra modifications or tuning are needed for installation.

This pipe is a straightforward way to improve airflow efficiency, leading to a more responsive throttle and quicker turbo spool-up. It addresses common weak points in the factory setup that can fail under demanding use. Installation is simple using basic hand tools.
