1979 L82 EGR Valve Assembly
Keep Your L82 Breathing Right—Restore Emissions Performance with Confidence
Your 1979 Corvette L82 deserves to run as strong and clean as it was designed to. This EGR Valve Assembly is a direct replacement for the factory-installed unit and is built to meet or exceed OEM specifications. Designed specifically for the high-performance L82 small-block engine, it replaces General Motors part number 17063994 and restores the proper exhaust gas recirculation function that’s key to both emissions control and efficient combustion.
The EGR (Exhaust Gas Recirculation) valve plays a crucial role in regulating cylinder temperatures, reducing NOx emissions, and maintaining proper air/fuel ratios. When it fails, you’ll often experience rough idling, poor acceleration, and failed emissions tests. This precision-engineered valve solves those issues while maintaining factory-correct fit and function for your 1979 Corvette.
Why It Matters:
A faulty or sticking EGR valve can rob your Corvette of its performance edge and cause compliance headaches during inspections. This replacement not only restores driveability but keeps your L82 running clean and efficient—without sacrificing its muscle car heritage.
