Yep. I have one. You can read more about the valve here: NGR Type-S Information
Yes, I know the website looks bad, but the product they make is excellent. The fitting of this valve however has been a pain so far. It’s not actually in the car at the moment because I have had to create a fitting kit out of a Greddy Type – RS adapter (wrong thread size), some 32mm ID radiator hose and 4 jubilee clips. I’m pretty sure this will work. Guess I’ll just have to find out!
I’ll keep you posted.
