Looks great. But is there a way to tell the level inside? Like a viewing window?

I already have Cobb overflow tank it’s high quality

The screws should also be black color or something cool like titanium hardware. Should also be a type of level gauge. The outside/inside black anodizing looks good.

So happy this came in my new fmic kit! Wasn’t sure if I ordered before the release.

Wish there was a way to see the level of coolant.

I just got mine today! Super excited to install. Quick question I know it wasn’t mentioned but do I need a tune for this?
