ISR Performance Colder Thermostat for VQ35HR and VQ37VHR Engines
If you're looking to optimize your Nissan's cooling system, the ISR Performance colder thermostat is a must-have upgrade for your VQ35HR or VQ37VHR engine. Designed specifically for high-performance applications, this thermostat opens at a cooler 68 degrees Celsius compared to the factory setting of 78 degrees Celsius. This means your engine can cool down faster before heat becomes an issue, allowing for improved performance and longevity.
How It Works
Once your engine reaches operating temperature, the ISR thermostat opens earlier than standard thermostats, enabling coolant to circulate through the engine sooner. This not only helps to maintain lower engine temperatures but also reduces the risk of overheating during spirited driving or track sessions. By keeping temperatures in check, you can push your engine harder without the fear of heat-related failures.
Fitment
- Nissan VQ35HR
- Nissan VQ37VHR
Important Note
- This thermostat is intended for use in competition vehicles that are not registered, licensed, or used on public streets or highways, as well as other exempted vehicles.
Customer Feedback
"I installed the ISR thermostat on my 2008 350Z, and the difference is noticeable! The engine runs cooler, especially during track days. I can push it hard without worrying about overheating." - 350Z Owner
"Swapped out the stock thermostat in my 2020 Infiniti Q50 with this ISR unit. It made a huge difference in keeping the temps down during spirited drives. Highly recommend for anyone looking to keep their VQ engine cool!" - Q50 Owner
