Product Description

The BBK 1710 80mm Power Plus Series Throttle Body is a direct bolt-on performance upgrade engineered for 1996-1998 GM trucks and SUVs equipped with the Vortec 305 or 350 V8 engine. By replacing the restrictive factory throttle body with a significantly larger 80mm bore, this BBK unit delivers up to 30% more airflow to the engine, resulting in 7-12 rear-wheel horsepower gains along with noticeably sharper throttle response and improved acceleration across the RPM range - all without requiring any tune or ECU modifications.

Machined from high-quality 356 aluminum on state-of-the-art CNC equipment, the BBK 1710 delivers an exact OEM-quality fit and installs without modification using the included spacer plate, gaskets, and hardware. OEM-style die-stamped throttle linkages, double-sealed bearings, and O-ringed throttle shafts ensure long-term reliability while preserving factory cable-actuated drivability. CARB approved (E.O. D-245-17) and legal in all 50 states, this throttle body is the ideal bolt-on upgrade for any GMT400 platform truck or SUV owner looking to extract more power from their Vortec V8.
