BBK Throttle Bodies 1543 Editorial Review
The BBK 1543 Twin 52mm Throttle Body is a high flow power plus series throttle body that fits and runs great in a '94 vette. It provides a noticeable difference in pedal feel with increased difficulty in depress. Some customers have reported cosmetic defects and cheaply made replacement screws that are easy to strip. There have been mixed reviews regarding performance, with some customers experiencing high idle and poor shifting points, while others have seen a small increase in throttle response and low-end power gain. Overall, the installation is easy and the finish is nice, but there is room for improvement in terms of quality.
