ISR Performance Low Temperature Thermostat - Nissan VQ35DE - 68 Degree - IS-21200-31U13
This product will be available for sale in 2 weeks, but you can pre-order now to receive 10% discount!
Designed for Nissan vehicles equipped with the VQ35DE engine, the ISR Performance Low Temperature Thermostat is a critical cooling system upgrade for track-driven or high-performance street builds. By opening at a lower temperature (68°C) compared to the factory unit, this thermostat allows coolant to circulate through the radiator earlier, helping to manage engine heat soak and maintain stable operating temperatures during sustained high-load conditions.
This unit is a direct replacement for the stock thermostat, featuring a high-quality wax element for reliable operation. It bolts directly into the factory thermostat housing, making it an essential preventative maintenance item or performance upgrade when refreshing your cooling system.
- Opening Temperature: 68°C (154.4°F)
- Engine Compatibility: Nissan VQ35DE
- Optimizes cooling efficiency for performance applications
- Direct replacement for OEM thermostat
- Manufacturer Part Number: IS-21200-31U13
