{"product_id":"b58-engine-mounts","title":"B58 Engine Mounts","description":"The AKG Motorsport B58 Motor Mounts are premium, modular polyurethane components engineered to enhance performance for BMW G20 M340i (2019-current, non-xDrive), G22 M440i (2021-current, non-xDrive), and G42 M240i (2023-current, non-xDrive) models equipped with the B58 engine.\n\nThese mounts are constructed from AKG's exclusive U.S. Mil-Spec polyurethane compound, noted for its elasticity and memory, providing performance comparable to metal mounts without the harshness. They also feature 6061-T6 aircraft-grade aluminum and a fully rebuildable design. Manufactured in the USA under ISO 9001:2015 certified standards, each mount is precision molded and CNC finished in small batches to ensure a perfect fit.\n\nThe factory fluid-filled rubber mounts are prone to deflection under torque, allowing the engine and transmission to move, especially when worn. These solid, bolt-through polyurethane mounts prevent engine movement, ensuring effective power transfer to the wheels and increasing responsiveness. The NVH (Noise Vibration Harshness) increase is described as moderate to high, varying with compound choice and individual perception.\n\nImportant fitment notes include: these mounts are specifically for non-xDrive models of the G20, G22, and G42 chassis. Additionally, the passenger side motor mount requires a proper heat shield to be installed at all times. The material used for the transmission mounts must also be compatible with the material used for the motor mounts.","brand":"AKG Motorsport","offers":[{"title":"Default Title","offer_id":52686862319928,"sku":"MMB58GA","price":472.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0970\/4895\/3144\/files\/661657173.webp?v=1784877654","url":"https:\/\/store.motormia.co\/products\/b58-engine-mounts","provider":"MOTORMIA","version":"1.0","type":"link"}
