    GReddy Radiator Hose Adapter with Temp Gauge Fitting 38mm ( Part Number: 16401638)
    Fitting 3 years ago
    FozzieSTi
    Perfect fit in my Aftermarket Perrin Radiator Hose and works fine with my Defi Water Temp Sensor. I just dont like the clamps. I have to replace them with good quality clamps. But all in all awesome item.

    Beware Not NPT! 5 years ago
    anthonyjcarlino49695
    I bought this adapter and did not realize it was PT. I have autometer gauges and this adapter is now useless for me (autometer uses NPT), make sure you check the threads on your water temp sensor before purchasing.I give 4 stars because this adapter does not come with screw to ground the sensor wiring like many adapters do.

    Does what it says it does, and it does it good. Had it for about 6 month now. You can hide the sensor rotating it towards the ground so it is completely invisible. Just make sure you have proper install of the hoses and clamps - had some minor leakages due to worn hoses.

        A:  The outer diameter of your radiator hose for your BR-Z is roughly 39mm. This would be the adapter that you are looking for.

    • Q: Evo 8/9 size  Evo Fonda5 years ago

      what size should I be using on an Evo8/9?
      • 1 of 1 people found the following answer helpful

        A:  The inner diameter of the Evo 8&9 radiator hose is 33mm. We unfortunately do not carry a 33mm radiator hose adapter, but we have 32mm and 34mm, and either should work.
