I liked nothing of this item. It was too small and the indicator told me, "this item fits your 2000 Ford Mustang," which was what made me buy the cap. I should have known better... this wasn't the first time.

After reading the reviews about it fitting BMWs, I purchased it. And it sure does. I have a 1996 BMW Z3 with M44 engine. I'm building my own Brake Pressure Bleeder so this is perfect. Great price and fast shipping too.

This cap did not fit my 2007 Buick Rainer. If you buy a cap be sure to purchase a gasket as well. The gasket does not come with the cap. Without the gasket the cap will not seal tightly and dust might or will get into your brake fluid tank. Thanks it looks well made just did not fit my car.

This cap fit great on my 1987 BMW 325e e30. Feels like a nice quality plastic.

making a Pressure Power Bleeder for European cars. I suggest you buy the ATE Brake fluid from Amazon also. The prices are excellent and the delivery quick and right to your front door.

I bought this to make my own pressure bleeder but unfortunately this is not a suitable cap. There is no gasket and there is also a vent line cut through the threads so the cap doesn't seal properly. A better cap would be Mercedes 2024300014 which is only ~$10 at the dealership.
