The BBK 1542 Power-Plus Series throttle body is designed specifically for 1992-1993 GM LT-1 engines, featuring twin 58mm bores for improved airflow and throttle response. This high-performance upgrade replaces the restrictive factory throttle body to unlock additional horsepower and torque across the RPM range.

Key Features:

• CNC machined from high-quality 356 aluminum castings for precision fitment and durability
• Twin 58mm throttle bores significantly increase airflow over stock
• OEM die-stamped throttle linkages ensure reliable operation
• Double-sealed bearings and O-ringed throttle shafts prevent vacuum leaks
• Direct bolt-on replacement for factory throttle body
• Manufactured to OEM quality standards for perfect fit and function

This throttle body upgrade is an excellent choice for LT-1 engine builds ranging from mild street performance to aggressive track applications. The increased bore diameter reduces intake restriction, allowing your engine to breathe more freely and produce more power without sacrificing drivability.
