GMC Duramax Performance Air Intake - Wehrli - 3in Y-Bridge Kit - Deore Gold - 07–10. High-flow, bolt-together replacement for 2007.5–2010 LMM Duramax trucks, finished in Deore Gold.

This WCFab two-piece 3 in. Y-bridge replaces the weak, slip-fit OEM unit and eliminates known failure points under boost. Paired 3 in. intercooler pipes create a true 3 in. tract from intercooler to intake runners. Smooth mandrel bends and CNC-machined billet flanges help reduce restriction while retaining factory grid heater, throttle valve, and EGR connections. Works with the OEM passenger-side lower pipe or WCFab WCF100367 and requires no tuning. Includes silicone boots, stainless T-bolt clamps, MAP sensor seal, O-rings, up-pipe to EGR gasket, hardware, and a throttle valve support bracket. Manufacturer-rated at 36% more airflow than stock.
