Product Details

Doing some work on the engine of your 1996-1998 GM truck or SUV, maybe a tune-up or a more involved rebuild? If you're looking to get a bit more out of your Vortec 305 or 350 engine, swapping out the stock throttle body for a larger, high-flow unit like this BBK Power Plus Series 80mm throttle body can make a noticeable difference. It's designed to replace your factory throttle body directly, meaning you won't have to modify anything to get it installed. This upgrade is a popular choice because it increases the amount of air that can enter your engine, which can lead to improved horsepower, torque, and a snappier throttle response, all while working with your vehicle's existing computer tune.

This BBK throttle body is CNC machined from a new aluminum casting, giving you a well-built part that's ready for the road. It features double-sealed bearings and O-ringed throttle shafts to ensure a good seal and smooth operation. The 80mm bore is significantly larger than most factory throttle bodies, allowing for up to 30% more airflow. It comes with new gaskets and hardware, so you'll have everything you need for a straightforward bolt-on installation. Plus, it's 50-state CARB legal, so you can be confident about its emissions compliance.

This throttle body is specifically designed for cable-operated throttle systems and does not require a computer re-flash to see the performance benefits. Just remember, this part does not fit 1998 2500 models or any 1996-1998 GM 454 applications; for those, you'll need to look at a different part number.
