BBK Power Plus Series 80mm Throttle Body for 1996-1999 Chevrolet/GMC (V8-5.0L/5.7L) - 1710

Fits select 1996-1999 Chevrolet and GMC trucks, SUVs, and vans equipped with 5.0L (305) or 5.7L (350) Vortec engines. This BBK Power Plus Series throttle body is designed as a direct-fit replacement for the restrictive factory unit, providing up to 30% more airflow to increase horsepower, torque, and throttle response without sacrificing OEM-level drivability.

Each throttle body is CNC-machined from a high-quality 356 aluminum casting for precise tolerances and long-term durability. To ensure smooth operation and a leak-free seal, BBK assembles these units with OEM-style die-stamped throttle linkages, double-sealed bearings, and O-ringed throttle shafts. This 80mm upgrade is a true bolt-on component that works with your vehicle's factory tune, requiring no additional calibration.
