Hybrid Racing knows the advantages of using a low-temperature thermostat in high-performance or race environments are evident. Opening the thermostat's valve at a lower temperature allows coolant to flow more freely during low-load sections of the racetrack. This enables the radiator to effectively regulate the engine's temperature within the optimal range during high-load sections. If a cooling system is pushed to its limits at the racetrack and overheating becomes an issue, a low-temperature thermostat can often resolve this problem. It achieves this by allowing the radiator to perform more cooling at lower engine loads, thereby preventing or delaying overheating during high-engine loads.
This part is made specifically for the Honda / Acura B-Series, D-Series, and L-Series engines.
Low-temperature thermostats offer several advantages and are useful in various situations. Here are some key reasons why they are beneficial:
- Enhanced Engine Cooling: Low-temperature thermostats allow coolant to flow more freely at lower temperatures, improving the cooling efficiency of the engine. By opening the thermostat's valve at a lower temperature, they help maintain the engine within the optimal temperature range during high-load conditions. This can prevent overheating and ensure consistent performance, especially in demanding situations like racing or high-performance driving.
- Prevention of Temperature Hunting: Low-quality thermostats can cause temperature hunting, characterized by erratic fluctuations in coolant temperature. In contrast, low-temperature thermostats are designed to prevent hunting by controlling the flow of coolant more effectively. This stability in temperature helps avoid issues such as cracked cylinder heads and reduces strain on the cooling system.
- Improved Durability: High-quality, low-temperature thermostats, like those offered by Nippon Thermostat Co. Ltd in the provided context, undergo extensive durability testing. This testing includes heating and cooling cycles, vibration testing, and real-world testing in both road and race cars. As a result, these thermostats are built to withstand demanding conditions and have superior durability, reducing the risk of failure and ensuring long-lasting performance.
- Customizable Cooling Systems: Low-temp thermostats offer the flexibility to fine-tune the engine's cooling system. They allow for better control over coolant flow and temperature regulation, enabling enthusiasts and engineers to optimize cooling performance according to specific needs and preferences. This customization can be particularly valuable in racing, where precise cooling management is critical for maintaining optimal engine performance.
Overall, low-temperature thermostats provide improved engine cooling, prevent temperature hunting, offer durability, and allow for customizable cooling systems. These advantages make them a valuable component, especially in high-performance applications where maintaining optimal temperatures is crucial for engine performance and longevity.
Hybrid Racing's HYPERCOOL thermostats are produced by an OEM supplier that has been in existence since 1954; Their thermostats are used in over 50% of cars manufactured in Japan and are widely utilized in motorsports events such as Le Mans and WRC. The durability of thermostats is crucial, especially considering the potential consequences of a malfunctioning thermostat and subsequent engine overheating. To ensure durability, we conduct rigorous testing on their low-temperature thermostats, including various cycles of heating and cooling, vibration testing, engine bench testing, as well as real-world testing in both road cars and race cars.

Very comfortable
Size: 36" X 24", Color: Grey, Size: 36" X 24", Color: Grey
Very soft and dries fast. I did the scoot test on them to test the grip and they passed with flying colors. Got them on a limited deal and it was worth every penny. I will be purchasing more in different colors as there are plenty of options. I haven’t washed them yet but if there’s an issue, I will definitely update this review. They are nice and thick and fell good on your feet.

Nice shower mat
Size: 50" X 30", Color: Navy
I have had it for almost a month now and run it through the washer and dryer. Its nice and soft, decent size I did not use a measuring tape to check how precise the sizing is. Absorbs the water when I step out of the shower well and doesn't feel wet or let anything through. Stays in place on the tile floor. Only challenge has been the robot vacuum cleaner gets trapped on it about half the time, but this might just be a testament to its thick nature.

Soft and washes well.
Size: 30" X 20", Color: Grey
These are great rugs and I keep going back and buying more. They are such a good value for money and they wash really easily. They don't slide or shed and they are very durable. They are very soft.So far we have them in both bathrooms and next to our bed.

Great Purchase
Size: 24" X 24" Contour Rug, Color: Beige
I picked these rugs (I purchased 3 of them) because it said its for elongated toilets. I have elongated toilets so I ordered for each room, they are a little large. I thought they would fit the toilet perfectly and not be large where it moves away from the side of the toilet. they are all very soft, like a shag rug, nice and thick and they come in many colors. The only thing I would change is the price of the light grey rug.

Good mat, good price, 'nuff said.
Size: 30" X 20", Color: Grey
While the photo suggests that this mat is enormous, it is a pretty good size at 30 x 20 inches. The chenille is very soft and feels nice on your feet. There is a rubber backing that prevents slippage on smooth bathroom floors. Overall there is nothing terribly noteworthy about this bathmat - it's a nice, high quality mat at a very good price. A good deal every day.
