Wehrli 04.5-05 Chevrolet LLY Duramax Passenger Side 3in Intercooler Pipe - Sparkle Bomber Orange

You're getting a 3-inch cold side intercooler pipe for the passenger side of your 2004.5-2005 Chevrolet Silverado 2500 HD or GMC Sierra 2500 HD with the LLY Duramax engine. This kit includes the 3-inch mandrel-bent aluminum pipe, upgraded silicone boots, and stainless steel t-bolt clamps. The factory pipe is often a restriction and prone to blowing off under higher boost, but this Wehrli pipe is built to handle more pressure and improve airflow.

This pipe is a direct replacement for the stock 2.5-inch unit, and it's designed to fit without any other modifications, tuning, or upgrades needed. The straight connection at the intercooler helps improve airflow compared to the factory's angled boot. The upgraded silicone boots and t-bolt clamps create a more reliable seal, which means you won't be losing horsepower to boost leaks. The pipe itself is finished in a durable Sparkle Bomber Orange powder coat.

This setup is a solid option for improving the efficiency and throttle response of your Duramax. It's made in the USA and is designed to work with stock Y-bridges and crossover pipes. While it doesn't require tuning, it pairs well with emissions-compliant tuning and drop-in turbochargers if you're looking for more performance down the road.
