BBK Power Plus Series Twin 58mm Throttle Body for 1989-1993 Chevrolet, Pontiac, and GMC (1539)
This product will be available for sale in 2 weeks, but you can pre-order now to receive 10% discount!
Fits 1989-1993 Chevrolet Camaro and Corvette, Pontiac Firebird, and GMC Syclone and Typhoon models.
The BBK Power Plus Series twin 58mm throttle body is engineered as a high-flow, bolt-on replacement for the restrictive factory unit. By increasing airflow by up to 30%, this component improves horsepower, torque, and throttle response without requiring a custom PCM tune. Each unit is CNC-machined from a premium 356 aluminum casting to ensure precise tolerances and long-term durability.
Designed for easy installation and OEM-level drivability, this throttle body features double-sealed bearings and O-ringed throttle shafts for smooth operation and leak-free performance. The assembly includes OEM-style die-stamped throttle linkages for a direct fit to your existing cables.
- Twin 58mm bore design for increased intake volume
- CNC-machined from 356 aluminum casting
- Double-sealed bearings and O-ringed throttle shafts
- OEM-style die-stamped throttle linkages for direct fitment
- Compatible with factory ECU tune
