30lb Performance Fuel Injectors for 1985-1992 Corvette, Camaro & Firebird 5.7L L98 TPI
Proudly Accepting
High-flow performance for your modified L98 TPI. These 30lb performance fuel injectors are a professionally remanufactured Plug-and-Play solution for the 1985-1992 Corvette, Camaro, and Firebird 5.7L. Engineered to support increased horsepower demands, these injectors are ultrasonically cleaned, flow-matched, and rebuilt to ensure precision fuel delivery for your Tuned Port Injection system.
Support Your Performance Build
If you’ve modified your 5.7L L98 with bolt-ons, high-flow runners, or a performance cam, the factory injectors may no longer provide sufficient fueling. These 30lb Performance Injectors provide the extra headroom needed to maintain a safe air-to-fuel ratio under load while offering significantly better atomization than the original 1980s factory units.
Professional Rebuild & Quality Control
-
Advanced Atomization: Rebuilt using modern nozzle technology to produce a finer mist, resulting in cleaner combustion and more consistent power delivery across the RPM range.
-
Plug-and-Play Fitment: Designed as a direct physical replacement for the TPI fuel rail. These use the factory-style EV1 electrical connector—no adapters or harness modifications required.
-
Precision Flow Matching: Every set is dynamically flow-matched to within 1% to ensure perfect cylinder-to-cylinder balance, which is critical for preventing lean conditions in high-performance TPI builds.
-
Rigorous Testing: Each injector undergoes a multi-stage ultrasonic cleaning, leak testing at high pressure, and spray pattern verification before being calibrated to the 30lb/hr specification.
Vehicle Fitment:
-
Chevrolet Corvette: 1985–1991 (5.7L L98 TPI)
-
Chevrolet Camaro: 1987–1992 (5.7L L98 TPI)
-
Pontiac Firebird / Trans Am: 1987–1992 (5.7L L98 TPI)
-
Note: Due to the increased flow rate, ECU tuning/re-calibration is highly recommended for optimal driveability and performance.
