Product Details

The BBK 1534 Power-Plus Series throttle body delivers improved airflow and throttle response for 1985-1988 GM 305/350 TPI (Tuned Port Injection) engines. This twin 52mm bore design increases airflow capacity over the restrictive factory throttle body, unlocking hidden horsepower and torque across the RPM range.

Key Features:

  • CNC machined from high-quality 356 aluminum castings for precision fit and durability
  • Twin 52mm bore design optimized for TPI applications
  • OEM die-stamped throttle linkages for reliable operation
  • Double sealed bearings for smooth, long-lasting performance
  • O-ringed throttle shafts prevent vacuum leaks
  • Direct bolt-on replacement for factory TPI throttle body
  • Designed specifically for 1985-1988 GM 305ci and 350ci TPI engines

BBK Performance throttle bodies are engineered to meet or exceed OEM quality standards while providing measurable performance gains. The precision CNC machining ensures perfect fitment with factory components, making installation straightforward with common hand tools. Ideal for street performance, mild builds, or as part of a comprehensive TPI upgrade.
