Optimize your engine's performance and protection with the NISMO Low-Temp Thermostat 21200-RSZ30. Designed specifically for VQ35DE engines, this thermostat allows coolant circulation to be activated at a lower temperature than the original equipment model, reducing overheating and improving operating consistency under demanding conditions.
Opening temperature: ≈ 68°C (compared to the original thermostat ≈ 76.5°C) – opens earlier to maintain performance.
Compatibility: Nissan/Infiniti vehicles equipped with VQ35DE engines (and in some cases VQ35HR with minor modifications). Applies to 350Z , G35 in particular
Inclusions: Gasket provided to ensure optimal sealing.
Effect on performance: Faster start of coolant circulation, reduction of power losses due to high temperatures, better thermal homogeneity of the engine (useful in “sport” driving or extreme heat conditions).
Caution: In cold weather, the engine will take a little longer to reach optimum operating temperature, which may affect the interior heating. Also, on some VQ35HR engines, it will be necessary to block an additional cooling port and use bolts of the appropriate length.
