BBK Power Plus Series Twin 52mm Throttle Body for 1989-1993 Chevrolet, GMC, and Pontiac

Fits 1989-1993 Chevrolet Camaro and Corvette, GMC Syclone and Typhoon, and Pontiac Firebird models. This BBK Power Plus Series throttle body is engineered as a direct-fit replacement for the restrictive factory unit, offering a significant upgrade in airflow without sacrificing OEM drivability.

Each unit is CNC-machined from high-quality 356 aluminum casting to ensure precise tolerances and long-term durability. By providing up to 30% improved airflow over the stock housing, this twin 52mm design enhances horsepower, torque, and throttle response. The assembly features OEM-style die-stamped throttle linkages, double-sealed bearings, and O-ringed throttle shafts for smooth operation and a reliable seal. Designed to work with the factory engine calibration, this throttle body requires no aftermarket tuning for installation.
