That distinction matters: the whole assembly is MMX's, machined from 6061 aerospace-grade aluminum and finished in the MMX signature gloss black anodizing, so there is nothing plastic left underneath.\u003c\/p\u003e \u003cp\u003eEach cap arrives pre-sealed and pre-installed with an OE-spec valve and internal spring, which means there is no need to strip the valve assembly out of your factory cap and transfer it across. It is a genuinely plug-and-play swap: unscrew the old one, fit this one. A factory-spec Viton O-ring comes fitted, and an internally sprung clip gives the cap a secure and precise seat rather than the vague feel a worn plastic original develops.\u003c\/p\u003e \u003cp\u003eThe cap is compatible with applications using BMW OE part number 11 12 8 654 637.\u003c\/p\u003e \u003cp\u003e\u003cstrong\u003eProduct Details\u003c\/strong\u003e\u003c\/p\u003e \u003cul\u003e \u003cli\u003eFull OE cap replacement, not a cover\u003c\/li\u003e \u003cli\u003eDesigned and engineered in the UK\u003c\/li\u003e \u003cli\u003eCrafted from 6061 aerospace-grade aluminum\u003c\/li\u003e \u003cli\u003eAnodized in MMX signature gloss black\u003c\/li\u003e \u003cli\u003ePre-installed factory-spec Viton O-ring\u003c\/li\u003e \u003cli\u003eArrives pre-sealed with an OE-spec valve and internal spring fitted\u003c\/li\u003e \u003cli\u003eInternally sprung clip for a secure and precise fit\u003c\/li\u003e \u003cli\u003eNo need to transfer the valve assembly from the factory cap\u003c\/li\u003e \u003cli\u003eCompatible with BMW OE part number 11 12 8 654 637\u003c\/li\u003e \u003cli\u003eMMX part number: MMR03-1601\u003c\/li\u003e \u003c\/ul\u003e","brand":"MMX Performance","offers":[{"title":"Default Title","offer_id":67981408207002,"sku":"MMR03-1601","price":127.7,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0611\/7569\/3466\/files\/MMX-Performance-BMW-S58-B48E-Billet-Oil-Filler-Cap.jpg?v=1793133610","url":"https:\/\/apexmotorsportswa.com\/products\/mmx-performance-bmw-billet-oil-filler-cap-s58-b48e","provider":"Apex Motorsport","version":"1.0","type":"link"}
