GMC Sierra 2500HD Performance Air Intake – Wehrli Y-Bridge Kit, 3 in., Flat Black (2007.5–2010) replaces the restrictive LMM upper intake. It swaps the weak slip-fit joint for a rigid, bolt-together design that holds boost when you work the truck.

Engineered for the 2007.5–2010 Duramax LMM, it preserves a true 3 in. path from intercooler to intake runners. Mandrel bends and CNC billet flanges cut restriction and aid drivability, while retaining the grid heater, throttle valve, and EGR. Finished in flat black powder coat, the kit installs on stock trucks with no tuning required and includes quality clamps, seals, and brackets.

• Mandrel-bent tubing, CNC billet flanges, bolt-together seal
• Retains grid heater, throttle valve, EGR; no tuning needed
