24lb Genuine Bosch D3 Fuel Injectors for 1985-1992 Corvette, Camaro & Firebird 5.7L L98 TPI

Optimized Fueling for the 5.7L L98 TPI With Original GM Intake and Rails

The 24lb Bosch D3 injector is the go-to solution for Corvette and F-Body owners looking to replace unreliable factory Multec injectors. These Genuine Bosch Design 3 units feature a modern, slim-body composite construction that runs cooler than vintage metal-body injectors, effectively eliminating the hot-start issues common to the L98 platform.

Performance & Reliability Features:

• 24lb Flow Rate: A perfect upgrade for mildly modified 5.7L engines. These provide excellent atomization and are a direct replacement for factory 22lb units (standard tuning adjustments may be required for optimal performance).

• 4-Hole Disc Nozzle: Provides a fine mist spray pattern rather than a single stream. This results in more complete combustion, a crisper throttle response, and a smoother idle.

• Plug-and-Play Integration: Designed with the correct TPI length and EV1 electrical connector. No wiring adapters, spacers, or fuel rail modifications are necessary.

• Modern Fuel Compatibility: Constructed with internal seals that are 100% resistant to the corrosive effects of modern E10 Ethanol-blended pump gas.

• SouthBay Quality: Every set is dynamically flow-matched to within 1% to ensure perfect cylinder balance and reliable power delivery.

Vehicle Fitment:

• Fitment is based on Original Intake and Rails. Call if you have aftermarket intake.
