The GMC Sierra 3500 Performance Air Intake by Wehrli brings unrivaled innovation and efficiency with its 3-inch Y-Bridge Kit, available in a sleek gloss white finish. This kit is perfectly crafted for 2001-2004 Duramax LB7 models ensuring optimal airflow enhancement.

Engineered to replace the restrictive OEM Y-bridge and cold side intercooler pipe, this kit significantly boosts throttle response and turbo spool up. By creating a complete 3-inch intake tract from the intercooler outlet to the engine, you remove the need for the angled, failure-prone OEM intercooler boots. This modification facilitates 50% more airflow than the standard setup, enhancing your vehicle's performance manifold. Please note: this product should not be used with S300 or S400 style turbochargers and is incompatible with a Banks intercooler.
