Designed to address a small but common weak point in the engine bay, these billet aluminum caps offer improved durability, sealing reliability, and a refined OEM+ appearance.\u003c\/p\u003e\n\u003cp\u003eOver time, OEM plastic AC caps are prone to becoming brittle due to repeated heat cycles, age, and frequent removal during servicing. This can lead to cracking, poor sealing, and an untidy engine bay. MMX eliminates these issues by replacing plastic with a long-lasting CNC-machined 6061-T6 aluminum solution.\u003c\/p\u003e\n\u003cp\u003eEach cap is finished in anodized black, hand-polished, and engraved with a subtle MMX “X” logo to seamlessly match the MMX billet aluminum engine bay range. The result is a functional upgrade that looks purpose-built rather than aftermarket.\u003c\/p\u003e\n\u003cp\u003eMMX offers direct replacements for both OEM AC cap types, ensuring compatibility across a wide range of BMW and MINI platforms. This includes older R134A systems using black OEM caps, as well as newer R1234YF systems (circa 2017+) that use grey OEM caps.\u003c\/p\u003e\n\u003cp\u003eDesigned as true OEM replacements, the MMX billet AC caps are pre-sealed and install in seconds with no tools or modification required. They are fully reversible, require no AC system re-gas, and can be removed or returned to stock just as easily as the original parts.\u003c\/p\u003e\n\u003cp\u003eThis is a simple but effective upgrade for enthusiasts who care about longevity, detail, and a clean, well-finished engine bay.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eProduct Features\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003eCNC-machined from 6061-T6 aluminum\u003cbr\u003e\n\u003c\/li\u003e\n\u003cli\u003eAnodized black finish with engraved MMX “X” logo\u003cbr\u003e\n\u003c\/li\u003e\n\u003cli\u003eDirect OEM replacement design\u003cbr\u003e\n\u003c\/li\u003e\n\u003cli\u003ePre-sealed for quick, hassle-free installation\u003cbr\u003e\n\u003c\/li\u003e\n\u003cli\u003eFully reversible; returns to stock in seconds\u003cbr\u003e\n\u003c\/li\u003e\n\u003cli\u003eDesigned to match the MMX billet aluminum engine bay range\u003cbr\u003e\n\u003c\/li\u003e\n\u003cli\u003eNo AC system re-gas required\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003e\u003cstrong\u003eCompatibility\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eR134A Systems (Black OEM Caps)\u003c\/strong\u003e\u003cbr\u003eOEM part numbers:\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003e64 53 8 397 437\u003cbr\u003e\n\u003c\/li\u003e\n\u003cli\u003e64 53 8 387 438\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003e\u003cbr\u003e\u003cstrong\u003eR1234YF Systems (Grey OEM Caps)\u003c\/strong\u003e\u003cbr\u003eOEM part numbers:\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003e07 14 9 287 978\u003cbr\u003e\n\u003c\/li\u003e\n\u003cli\u003e07 14 9 287 979\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003e\u003cbr\u003e\u003cstrong\u003eFitment Disclaimer\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eWhile every effort has been made to ensure accurate vehicle information, customers are responsible for verifying compatibility with their specific vehicle and engine variant prior to purchase.\u003c\/p\u003e","brand":"MMX Performance","offers":[{"title":"R134A – Black OEM Cap","offer_id":49804179702006,"sku":"MMR03-0004","price":40.0,"currency_code":"USD","in_stock":true},{"title":"R1234YF – Grey OEM Cap","offer_id":49804179734774,"sku":"MMR03-0003","price":40.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/2674\/6278\/files\/54988491164_2da7dcf55b_b_a825d8e.webp?v=1766087894","url":"https:\/\/autotecknic.com\/products\/mmx-performance-billet-air-conditioning-caps","provider":"AutoTecknic USA","version":"1.0","type":"link"}
