Wells 4F1880 EGR Valve Exhaust Gas Recirculation Valve

The Wells 4F1880 EGR valve (exhaust gas recirculation valve) is an emissions control replacement part. 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 mixture
• Recirculated exhaust helps cool the combustion chambers, which lowers NOx formation
• Designed by Wells Vehicle Electronics to meet or exceed OE specifications for fit, form and function
• Manufacturer part number: 4F1880
• Cross-references to OE numbers 4L2Z9D475FB, 5L2Z9D475B, 2134446 and 226700

A failing EGR valve can cause a rough idle, stalling, hard starting, reduced power, lower fuel economy or an illuminated check engine light. Replacing it restores proper exhaust gas flow control and helps the vehicle pass emissions testing.
