BBK Power Plus Series Twin 52mm Throttle Body for 1985-1988 GM Camaro, Corvette, and Firebird (1534)

Fits 1985-1988 Chevrolet Camaro, Corvette, and Pontiac Firebird models equipped with 305 and 350 V8 engines.

The BBK Power Plus Series Twin 52mm Throttle Body (Part #1534) is a high-performance induction upgrade designed to replace the restrictive factory throttle body on early GM Tuned Port Injection (TPI) engines. Engineering for increased induction volume, this unit provides up to 30% more airflow over stock, resulting in improved throttle response, horsepower, and torque without sacrificing OEM drivability.

Each BBK throttle body is CNC-machined from a premium 356 aluminum casting to ensure precise tolerances and long-term durability. To maintain consistent performance and a smooth pedal feel, it features double-sealed bearings, O-ringed throttle shafts, and OEM-style die-stamped throttle linkages. This unit is a direct bolt-on replacement that works seamlessly with the factory ECU tune, requiring no additional programming or calibrations for installation.
