22lb Genuine Bosch D3 Fuel Injectors for 1985-1992 Camaro & Firebird 5.7L L98 TPI
Proudly Accepting
The ultimate reliability upgrade for your L98 350. These 22lb Genuine Bosch D3 fuel injectors are a direct Plug-and-Play replacement for the 1985-1992 Chevrolet Camaro and Pontiac Firebird 5.7L TPI. Featuring modern 4-hole nozzle technology, these injectors provide superior atomization, a rock-solid idle, and improved hot-start reliability compared to the factory originals.
The original factory injectors in the 1985-1992 L98 engines are notorious for failing due to modern ethanol-blended fuels and internal coil degradation. Our Genuine Bosch D3 (Design 3) 22lb injectors are the industry-standard solution. Their slim, composite-body design allows them to run cooler and resist the "clogging" common in older metal-body pintle injectors.
Why Choose Bosch D3 for your 350ci V8?
-
Advanced 4-Hole Spray Pattern: The Bosch D3 replaces the outdated single-stream spray with a fine 4-hole mist. This ensures more complete combustion, leading to crisper throttle response and better fuel economy.
-
Direct OEM Fit: No adapters or modifications required. These injectors are the correct length and use the factory-style EV1 electrical connector to snap directly into your TPI fuel rail.
-
Ethanol Compatible: Built with modern internal seals that are 100% compatible with E10 pump gas, preventing the leaks and sticking issues seen in vintage components.
-
Precision Matched: Each set is dynamically flow-matched to within 1% at SouthBay Fuel Injectors, ensuring perfect cylinder balance and easier ECU calibration.
