TMIC coolant expansion tank replacement?

[NORAGRETS]

I know RK makes a titanium version of the TMIC expansion tank, does any other company make a metal/aluminum replacement for this? I believe forge makes one, but it's part of the TMIC (have to purchase the tmic to get it).

My OEM one shit the bed and I need a new one asap any help appreciated

Turner makes one. I assume the oem one has baffles to prevent air bubbles but never seen one cut open.
If they're anything like the coolant reservoirs in the old NSX's, it was proven that the oem tanks were far superior to the aftermarket ones due to the inner baffles preventing excessive air bubbles in the system during cornering.
I would just get a new oem one, they're cheap and do not transfer/absorb heat.

But they do fail continuously…never owned a bmw that did not have a OEM reservoir crack…

I'd get an OEM unit from FCP Euro. You know it will fit right, and you can always exchange it if you had a subsequent problem.

I misspoke. It was Forge brand I was referring to.
I just had my oem replaced with oem one a few weeks ago. Very small leak at end of warranty.

Yeah, not sure on that. I only know that they "make" one. I would just go oem, new and be done. Same goes for the after cooler.

Here's a question for everyone, do your coolant reservoirs have obvious gaps on one side on the tank and on the other looks sealed? Mines like this but it seems to be manufactured as such and not cracked like I thought it was

Yes, my factory units always had a cruddy weld line, but they all held fine.
