The Mishimoto racing thermostat and housing for 2009–2025 Nissan GT‑R opens at about 66°C and is intended to promote greater cooling efficiency for twin‑turbo engines. By opening at a lower temperature than many OEM units, it allows coolant to flow earlier once the engine warms, helping reduce and maintain lower operating temperatures during demanding or sustained driving conditions.
