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 aluminum cap is much more sturdy and features a standard 19mm hex post on the top. 19mm is also the size of your engine oil drain plug, reducing the number of tools that you need to complete an oil change. 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.

Designed to fix a known weak point for the MINI B3X and B4X engines, the ECS billet aluminium oil filter housing cap is a direct replacement for the factory plastic cap. The OEM plastic part is infamous for cracks, stripped threads, and rounded hex heads—often failing during routine oil changes and turning basic maintenance into a frustrating, time-consuming repair.

The engineers at ECS have designed a precision-machined billet aluminium upgrade that eliminates those issues, delivering strength, durability, and consistent fitment. An integrated drain plug allows you to drain the filter housing cleanly before removal, reducing spills and mess for a faster, cleaner oil service.

Replaces OEM MINI part number 11428575907.

FEATURES

Fixes common OEM plastic failures, including cracking, stripped threads, and rounded hex heads Precision-machined billet aluminum construction for superior strength and longevity Black anodized coating to prevent oxidation Integrated drain plug allows clean, mess-free oil changes Improves serviceability, reliability, and underhood appearance
