The Chevrolet Duramax Performance Air Intake by Wehrli, featuring the 3in Y-Bridge Kit in CAT Yellow, is tailored for the 2001-2004 Duramax LB7 engines. This kit replaces the restrictive OEM Y-bridge to deliver enhanced performance and an aggressive aesthetic for your truck.

Engineered to provide a significant airflow improvement, this 3-inch Y-Bridge Kit is the only high flow option on the market compatible with the factory IHI turbo and similar aftermarket chargers. By increasing the throttle response and turbo spool through a full 3-inch intake tract from the intercooler outlet to the engine, it transforms driving dynamics, while eliminating failure-prone angles of OEM boots. The included FPRV Block off kit ensures proper clearance for a larger diameter Y-bridge, although it's worth noting that it's not compatible with S300 or S400 style turbochargers. If you're considering a non-OEM turbo setup, alternative kits are recommended.
