Mishimoto racing thermostat for the Nissan 300ZX, Maxima, Pathfinder, Frontier, Quest and Xterra with the VG30 / VG33 V6 (and related Infiniti J30/M30/QX4). Opening at 68°C / 155°F — lower than stock — it lets coolant flow through the engine sooner to reduce and maintain cooler temperatures. Direct-fit replacement, backed by the Mishimoto Lifetime Warranty.
