Starline EGR Valve 42459019S Ford Transit 06-13

An EGR, or Exhaust Gas Recirculation valve is a means of reducing NOx (Nitrogen Oxide) emissions from your engine. The EGR valve, as its name suggests, re-circulates exhaust gases to act as a coolant in the combustion chambers.Over time EGR valves become sticky and will eventually seize open or closed. If seized open the engine may idle poorly or even stall. If seized closed the engine will operate at increased temperatures under load and may cause "engine knock". This is especially bad for turbocharged vehicles, as the increased exhaust gas temperature can lead to premature failure of the turbocharger also.
