After the third time we tried to get it installed (in various ports, etc) and having leaking problems, we finally got it to work by using the Greddy water pipe adapter. It took 3 weeks to get here from Japan and it was such a mint looking piece

it goes well with the Greddy oil filter block..

you have to retap it too, since it comes in 1/8 BSPT.. but once you do that, it fits like a glove..

I am getting 190-200F constant.. so i am a happy camper
