Detailed Description

Standard Ignition EGV534 is an exhaust gas recirculation valve used to regulate exhaust flow back into the intake stream on emissions-controlled engines. This part number is a direct replacement for vehicles such as the Chevrolet S10, Chevrolet Astro, GMC Sonoma, Buick Century, and Pontiac Fiero, with coverage across multiple 1984-1993 applications. This part cross-references Monroe Shocks & Struts (e.g., 172286, 182286) for the same application.

The valve’s stainless steel construction supports long-term durability, while the reinforced silicone diaphragm is built to handle elevated operating temperatures. The included gasket helps complete the replacement at the mounting surface, and the electronic 5-terminal configuration supports the original vehicle setup.
