{"product_id":"m157-billet-polyurethane-engine-mounts","title":"M157 Billet Polyurethane Engine Mounts","description":"The BenzUnited Parts M157 Billet Polyurethane Engine Mounts are engineered to enhance the performance of Mercedes-AMG M157 (5.5L BiTurbo) powered vehicles. By significantly reducing engine movement and drivetrain lash, these mounts deliver a noticeably sharper throttle response and more consistent power transfer, especially under load, making them ideal for tuned or aggressively driven AMGs.\n\nConstructed from robust billet aluminum and high-durometer polyurethane, these engine mounts are built to withstand the demands of high-performance driving. The materials are chosen for their resistance to heat, oil, and deformation, ensuring longevity and consistent performance.\n\nFitment is exclusive to the W212 E63 AMG\/E63 S AMG (2012–2016) and W218 CLS63 AMG\/CLS63 S AMG (2012–2018) models equipped with the M157 engine. Installation involves reusing the OEM top cap and requires professional installation to be recommended. It is advised to torque all fasteners to factory specifications and to verify clearance for the downpipe and steering rack post-installation.\n\nWhile a slight increase in vibration at idle may be normal, most drivers find the added precision and elimination of drivetrain slop to be a worthwhile trade-off for spirited driving. These mounts are specifically designed to handle the elevated torque and heat common in tuned M157 builds.","brand":"BenzUnited Parts","offers":[{"title":"Default Title","offer_id":52687119417656,"sku":"M157-ENGMOUNT-CLS","price":495.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0970\/4895\/3144\/files\/662153247.webp?v=1784880534","url":"https:\/\/store.motormia.co\/products\/m157-billet-polyurethane-engine-mounts","provider":"MOTORMIA","version":"1.0","type":"link"}
