Wehrli 2004.5-2005 LLY Duramax Passenger (Cold) Side 3in Intercooler Pipe- WCFab Grey

This kit includes a 3-inch mandrel-bent aluminum intercooler pipe, silicone boots, and stainless steel t-bolt clamps. It's designed to replace the factory 2.5-inch passenger side intercooler pipe on your 2004.5-2005 LLY Duramax truck. The factory pipe can be a weak point, prone to blowing off under higher boost pressures, which robs your engine of power and can cause drivability issues. This updated pipe addresses those weaknesses with a larger diameter and stronger connection points.

The pipe is constructed from 14-gauge aluminum and features a high-flow, mandrel-bent design that improves airflow between the turbo and the engine. This can lead to better throttle response and quicker turbo spool-up. The included silicone boots and t-bolt clamps are built to handle higher boost pressures than the stock components, increasing reliability and preventing boost leaks. It's a direct bolt-on installation that doesn't require any modifications, additional parts, or tuning, making it a straightforward upgrade.

This intercooler pipe comes finished in a durable WCFab Grey powder coat. It's designed to work with the stock Y-bridge and crossover pipe, making it compatible with trucks that haven't had other modifications. While it improves airflow and efficiency on its own, it pairs well with emissions-compliant tuning and drop-in turbochargers for even greater performance gains.
