Carquest Premium – Exhaust Gas Recirculation (EGR) Valve (Part No.EGC1221)

Exhaust Gas Recirculation (EGR) Valve

from

$47.99
The EGR system is an emission control device designed to recirculate exhaust gas into the engines air intake system and back to the combustion chamber to control nitrogen oxides or NOx. The chemical NOx is created when oxygen and nitrogen are heated above 2,800-degree F. Exhaust gas, or gas that is displaced from the combustion chamber, contains little to no oxygen molecules. By recirculating this gas back into the combustion chamber fewer oxygen molecules are available for the combustion event which will therefore create a cooler combustion event. The EGR valve can be actuated by engine vacuum or electronically by the engine control module.

Product Features:
  • Product constructed to meet all design and operating characteristics as intended by the vehicle manufacturer.
  • Our EGR valves are designed to match the vehicle specific exhaust gas flow rate as designed by the engine manufacturer to provide clean tail pipe emissions.
  • Feedback EGR valves and pressure sensors contain a robust circuit board design which increases durability due to heat, shock, and random electro-magnetic pulses (EMP) and power spikes.
  • 100% thermo-shock and vibration tested to ensure superior performance in extreme conditions.
  • Where applicable stainless-steel sleeves used over cold rolled sleeves providing smooth EGR pintle operation under all operating conditions.
