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

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.
The factory E9X oil filter housing cap is made of plastic which, by nature of the material, dissipates heat poorly and is prone to failure over repeated heat cycles. By contrast to the OEM unit, our cap is constructed from 6061-T6 aircraft-grade aluminum which promises two functional benefits: greater longevity and cooler running throughout its life cycle.
So too will the oil itself benefit: By getting your oil up to temperature quickly, but tangentially evacuating excess heat, the aluminum oil filter housing cap will help your fluid operate within its working range while effectively preventing thermal breakdown.
Each cap has been meticulously manufactured on a DMG Mori 5-Axis with specially sourced tooling to achieve some of the cap's intricate details. Anodized, the housing cap’s details are happily preserved but offer up a valuable way for an enthusiast to express their individuality. Four colors are available at launch to maximize choice: Ferrari Red, Royal Blue, Hard Coat Clear, and Hard Coat Black.
Appropriately, our latest livery box echoes a Gulf theme—echoing our motorsport intent and ties to the culture that has inspired us to create from the beginning.
