Cool Combustion: Exhaust Gas Recirculation (EGR) Valves
The EGR Valve is critical for preventing engine "pinging" (detonation) on 1970s and 80s vehicles. It recirculates a small amount of inert exhaust gas back into the intake to lower combustion temperatures.
Symptoms of Failure
Stuck Open: Rough idle, stalling, and poor performance.
Stuck Closed: Engine pinging/knocking on acceleration and higher NOx emissions (failed smog test).
NOS and NORS Quality: We stock authentic USA-Made EGR valves (often from brands like Standard, Tomco, or Wells) that feature heavy-duty diaphragms designed to withstand exhaust heat better than cheap imports.
