Thermostat 82 Deg Hiflow – WP25017 This high‑performance thermostat is engineered for A‑series engines, featuring an 82‑degree Celsius opening temperature that promotes earlier coolant flow and improved thermal control. Its valve design incorporates a 37% increase in effective opening area, allowing significantly greater coolant passage compared to standard units. Combined with optimized internal geometry, the thermostat delivers approximately 30% higher flow rate at a given system pressure, reducing thermal bottlenecks and helping maintain consistent operating temperatures during high‑load or high‑RPM use. The result is enhanced cooling efficiency, reduced risk of heat soak, and improved overall engine stability. A stable engine temperature is imperative on modern engine management systems Alternative for GTS1104, GTS280, GTS1102 SKU: WP25017 Category: Go
