So why upgrade to these three high performance lifetime replacements?\u003c\/p\u003e\n\u003cp\u003eFirst of all, our high performance stainless steel oil filter removes the notorious B58 oil filter disintegration problem forevermore. By replacing the factory paper filter element with MMR’s advanced high-flow, high-filtration stainless steel filter unit, you will protect your engine from the big bills (and potentially worse) caused by the OE filter’s well-documented collapse failure.\u003c\/p\u003e\n\u003cp\u003eAs well as this exceptional filtration, the lifetime filter material allows for five times the flow of comparable paper oil filters. Its design provides consistent filtering across entire filter surface.\u003c\/p\u003e\n\u003cp\u003eAs the perfect complement to your new filter, the billet oil filter housing is a direct replacement housing that replaces the cheap plastic oil filter housing which is fragile and often cracks, leading to oil leaks. Of course, the gloss-black, solid billet of 6061 aerospace-grade aluminium is a thing of beauty in the engine bay. But, it's certainly not just about the looks. An integrated pressure control oil bypass is built into the MMR housing, meaning that there is no need to transfer OE plastic bypass valve from OE filter housing to MMR filter housing.\u003c\/p\u003e\n\u003cp\u003eThe last piece of this kit is our best-selling magnetic sump\/oil pan plug. It’s one of the simplest yet most effective upgrades that you can install into your engine to increase its lifespan. As an engine wears, tiny metallic particles become suspended in the oil, accelerating wear each time you drive. Our magnetic sump plugs will help to separate these ferrous particles out.\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003e1 Series F20\/F21 M140i\u003c\/li\u003e\n\u003cli\u003e2 Series F22\/F23 M240i\u003c\/li\u003e\n\u003cli\u003e3 Series F30\/F31 M340i\u003c\/li\u003e\n\u003cli\u003e4 Series F32\/F33 M440i\u003c\/li\u003e\n\u003cli\u003e\u0026amp; More\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003e1 -Series, 2-Series, 3-Series, 4-Series, Z4 \u0026amp; Toyota Supra\u003c\/p\u003e\n\u003cp\u003eF2x, F3x, F4x, G2x, G4x, G29 \u0026amp; J29 B57 \u0026amp; B58 M140i, M240i, 340i, 440i, 540i, 640i, 330d \u0026amp; 430d 2011+\u003c\/p\u003e","brand":"MMX","offers":[{"title":"Default Title","offer_id":56286852415872,"sku":"MMR17-1500FK","price":213.6,"currency_code":"GBP","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0720\/7557\/5573\/files\/MMX_Oil_Change_Service_Kit_Bundle_for_BMW_B58_B57.webp?v=1765981961"},{"product_id":"mmx-gear-shift-paddles-g-series-titanium-magnetic-paddle-inc-fitting-kit","title":"MMX Gear shift paddles | G Series | Titanium Magnetic Paddle Inc Fitting kit","description":"\u003ch3\u003eWelcome to the ultimate pair of billet magnetic shift paddles for BMW G-Series vehicles including LCI.\u003cspan\u003e \u003c\/span\u003e\n\u003c\/h3\u003e\n\u003cp\u003ePut yourself back in control of your BMW, and boost your interior aesthetics with these exquisitely engineered billet magnetic aluminium paddles.
