Mishimoto racing thermostat for the 1989-1998 Nissan 240SX (KA24DE or SR20DET swap) and related Nissan/Infiniti 2.0-2.4L applications. 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.
