Wells 4F2110 EGR Valve Exhaust Gas Recirculation Valve

The Wells 4F2110 EGR valve (exhaust gas recirculation valve) is a replacement emissions-control component. It helps reduce nitrogen oxide (NOx) emissions by sending a portion of the exhaust gas back into the engine's combustion system.

Key Features:

• Opens and closes to control how much exhaust gas mixes with the incoming air/fuel charge to be burned again
• Recirculated exhaust helps cool the combustion chambers, which lowers NOx formation
• Designed to meet or exceed OE specifications for fit, form and function
• Made by Wells Vehicle Electronics, a brand specializing in emissions and engine management components

An EGR valve is generally mounted on or near the intake manifold. Signs of a failing valve include rough idle, stalling, hard starting, decreased power and reduced fuel economy. Replacing a faulty EGR valve can help restore smooth engine operation and emissions system performance.
