Billet Coolant Flanges! - AHU / 1Z

[Windex]

If I still owned one, I would be all over this, as the plastic design lasts about 100k before needing to e replaced.

I know I come across like a shill, but actually have no relation to the seller, other than wanting to buy one just in case I ever get another B4...

I may be participating in that group buy here too.

I've thought about this before. It's not too difficult to make, it would likely take an afternoon to program and make a couple. Since the head is likely 356T6 aluminum (or its European equivalent), 6061T6 is the material of choice.
