BBK Twin Throttle Body GM TPI

The BBK Twin Throttle Body for GM TPI is a direct-fit replacement throttle body for tuned port injection (TPI) small block Chevy engines. It is designed to improve airflow, throttle response and acceleration over the factory unit. BBK Performance designs and manufactures these twin-bore throttle bodies in the USA.

Key Features:

• Twin-bore design that increases airflow to the engine compared with the stock throttle body
• CNC machined from high-quality 356 aluminum castings for OEM-quality fit
• Die-stamped throttle linkages, double-sealed bearings and O-ringed throttle shafts
• Direct-fit replacement for straightforward installation
• BBK states a gain of 7-12 rear-wheel horsepower, depending on the vehicle and application
• CARB-approved under EO D-245-15 for the GM applications listed by BBK
• Backed by a 1-year factory warranty

BBK Performance throttle bodies are built to bring quicker throttle response and stronger acceleration to TPI engines. They suit street performance builds and mildly modified setups, and they work well alongside intake and exhaust upgrades.
