PentRoof JZZ30 Stainless Upper Water Bypass Kit (without VVT-i)

By bypassing the cooling water from the heater hose to the radiator upper hose, the water flow path was reduced and a sufficient amount of cooling water circulation was secured.
This stabilizes the temperature of the rear cylinder, where heat tends to accumulate, and prevents heat dripping and overheating of the engine while controlling the rise in water temperature.
Recommended for circuit driving.

In addition, the radiator upper hose is replaced with a dedicated SUS pipe, and the coolant is circulated efficiently by suppressing the expansion and crushing of the radiator hose.
The SUS upper has a mounting port for the water temperature sensor.
