EGR Valves

As its name suggests, the exhaust gas recirculation valve – EGR valve for short – recirculates finely metered quantities of exhaust gas to the engine intake system. By simply altering the chemical makeup of the air entering the engine and thus lowering the temperatures in the combustion chamber, it reduces the production of NOx for a much cleaner, more efficient exhaust. With so much at stake, you’ll want to fit a quality brand with proven OE technology…just like ours.
