Fits 2022 Tesla Model S
I bought this to replace the DOT3 cap on a 2022 Tesla Model S Plaid after upgrading to Carbon Ceramic Brakes with DOT 5.1 fluid from the service center. They don't swap out the cap. Since they don't make DOT 5.1 caps, I opted for a DOT 4 cap. This fit perfectly without any leaks.

Fits my 2018 Camaro
Works perfect for 2018 Camaro ZL1 1LE. I replaced the stock fluid with DOT 4 for track use and wanted to make sure the cap stated the correct fluid.

Does not work on my 2015 Corvette.
I was under the impression that this cap would work on my car but it does not tighten down.
