GMC Sierra 2500HD Performance Air Intake - Wehrli - Y-Bridge Kit - Brizzle Blue - '06-'07. A high-flow 3-inch two-piece bridge and charge pipe upgrade for 2006-2007 Duramax LBZ trucks, built for reliable airflow under boost.

The OEM slip-fit Y-bridge is known to separate on hard-working LBZs. WCFab’s bolt-together 3-inch bridge creates a secure sealing surface at the air inlet horn, while matching 3-inch upper and lower intercooler pipes use smooth mandrel bends and CNC-machined billet flanges for a full 3-inch tract from intercooler connection to engine. It retains factory grid heater and EGR connections, works with the OEM lower passenger-side intercooler pipe or WCFab’s 3.5-inch WCF100367, wears a durable Brizzle Blue powdercoat, and offers up to 36% airflow improvement over stock. No tuning required; direct bolt-on; made in the USA.
