BBK 98-03 Camaro Firebird GTO LS1 85mm Throttle Body BBK Power Plus

BBK CNC machines these throttle bodies from a new aluminum casting, and they assemble them with features like OEM-style linkages, double-sealed bearings, and O-ringed throttle shafts. This attention to detail means you get OEM-level driveability with the performance gains you're looking for. A notable benefit is that these throttle bodies work with your vehicle's factory tune, so no reprogramming is needed after installation. They also come with a spacer plate, required gaskets, and hardware, making it a straightforward bolt-on upgrade.

This BBK throttle body is a solid option for many popular GM LS1 applications from 1998 through 2004, including Camaros, Firebirds, GTOs, and several Silverado and Sierra truck models. It's also 50-state CARB legal, which is a plus if you're in California or another state with strict emissions requirements.
