Walker Products Exhaust Gas Recirculation (EGR) Valve P/N:570-5043

Walker Products 570-5043 EGR Valve

Walker Products EGR Valves are OE Replacement components that restore precise exhaust flow control for improved emissions, efficiency, and drivability.

• Walker Products Exhaust Gas Recirculation (EGR) Valves are OE Replacement components engineered to restore factory emissions performance and drivability by accurately controlling the flow of exhaust gases into the intake manifold. By reintroducing a portion of exhaust gas into the combustion chamber, EGR valves reduce peak combustion temperatures—significantly lowering nitrogen oxide (NOx) emissions and improving engine efficiency. Walker EGR valves are manufactured to meet or exceed OE specifications for flow rate, actuation timing, electrical connectivity, and valve position control. Available in both vacuum-operated and electronically controlled formats, each valve is designed for an exact OE fit with original mounting locations and connector types. Built from heat- and corrosion-resistant materials, these valves are designed to withstand extreme under-hood conditions and continuous exhaust gas exposure. Whether addressing emissions-related fault codes, resolving rough idle, or performing routine service, Walker EGR Valves help restore proper engine function, reduce emissions, and support long-term compliance with federal and state regulations.
• Reduces NOx Emissions:Recirculates exhaust gases back into the intake to lower combustion temperatures and reduce emissions.
• Restores Engine Efficiency:Helps resolve rough idle, hesitation, and poor fuel economy caused by faulty or sticking EGR valves.
• OE Replacement Design:Matches original equipment specifications for flow rate, response time, and electronic control compatibility.
• Exact OE Fit:Installs directly into factory mounting points and connects to original wiring and vacuum systems—no modification required.
• Built for Harsh Conditions:Constructed from corrosion-resistant materials to withstand heat, soot, and constant exhaust flow exposure.
