Pacific Performance Engineering (PPE) 2006–2010 GM 6.6L DURAMAX OEM LOWER INTAKE MANIFOLD LBZ/LMM - Passenger Side

An intake manifold kit replaces the factory passage that feeds air into the cylinders, usually with a larger, smoother path. This one is the Pacific Performance Engineering 2006–2010 GM 6.6L DURAMAX OEM LOWER INTAKE MANIFOLD LBZ/LMM - Passenger Side, listed to fit the 2006-2010 Chevrolet Silverado 2500HD/3500HD with the 6.6L Duramax V8 (LBZ) or 6.6L Duramax V8 (LMM).

why this one — On its own it is a supporting part. The gain shows up alongside other airflow and fuel changes, and a tune usually comes with it. PPE Direct lists it at $139.99, and the fitment above is what the listing itself states, not a guess.
