BMW uses a lot of plastic in their engine components to save weight and money. Unfortunately, plastic is damaged easily and the factory oil filter cap needs a special tool to remove. This cap is designed to use the original o-ring seal so no special parts are required. You only have to remove the original 'filter cage' from the original cap and transfer it to the new aluminum cap. The satin black anodize blends in with the rest of your engine bay making this a smart and subtle upgrade.

Here is a link to the original Genuine BMW oil filter cap if you are looking for that instead.
