GReddy FR-S / BRZ Upper Water Temperature Adapter

This GReddy upper water temperature adapter is what you get when you want to install an aftermarket water temperature gauge on your 2013-2020 Subaru BRZ, Scion FR-S, or Toyota 86. It replaces a section of your upper radiator hose, giving you a convenient port to thread in your temperature sensor. This makes getting an accurate reading of your engine's coolant temperature much simpler than trying to tap into other parts of the cooling system.

Built from durable aluminum, this adapter is well-made to handle the heat and pressure found in your cooling system. It's designed to fit right into the factory hose routing, so you won't have to do any custom fabrication. The threaded port is a standard size, commonly used for aftermarket temperature sensors, making it easy to connect your gauge setup. Having a reliable water temperature reading is important for monitoring your engine's health, especially if you've made modifications or drive your car hard.
