Genuine Maruha part, 78° Thermostat.

Maruha 78 Thermostat, our hot-selling item in Japan where MIATA was born, is the most suitable accessory for tuned cars.
The product has great advantage of circulating coolant through a radiator to be cooled with its high lift valve in large diameter.
The valve is open fully at lower temperatures than the MIATA genuines.

The NA8C, featuring the main and sub valves, has disadvantage of the water circulation because of the small valve diameters.
Besides the valves, the rod lengths are too short to send the coolant smoothly into the radiator .
The NB brings several improvements in the opening temperature and in the valve diameter.
MIATA NB thermostat has the valve off-centered from the center of the thermostat to make room for the jiggle valve to let out air bubbles
Furthermore, the thermostat housing includes the off-centered water passage to help the thermostat valve to connect the housing with the passage center line.
The ideals is that the centers of the valve and of the water passage are arranged in a line, though the NA8C thermostat cannot send the coolant smoothly as the minimum-sized main valve is extremely off-centered to place the sub.

Maruha 78 Thermostat is named for its opening temperature at 78 degrees (c), which provides the stable engine performance with the excellent cooling capacity in sports driving.
The product is designed to start opening the valve at about 5 degree (c) - 10 degree (c) lower than the MIATA genuines.
Furthermore, the Maruha's product has the 31.5 mm diameter valve to be opened fully at 92 degree (c) and the 10 mm long rod allows more water to flow into the radiator.
These features enable to perform the radiator effectively and to increase the cooling performance in severe driving conditions.
This product should be installed by a professional.
