{"product_id":"pulleys-s54-engine","title":"Pulleys (S54 Engine)","description":"The Rogue Engineering Power Pulley Kit is engineered to unlock additional power from your S54 engine by reducing the parasitic drag created by accessory pulleys. By slowing down the rotation of the water pump and power steering pump, the engine can dedicate more of its output to generating power, leading to noticeable gains in torque and overall performance. This kit is designed with a calculated percentage reduction based on factory dimensions, ensuring that accessory functions are safely maintained without compromising efficiency.\n\nThey feature a military-spec MIL-A-8625 Type III hardcoat anodized finish, which provides exceptional wear resistance and a robust surface layer. The lighter weight of the pulleys also contributes to a small boost in throttle response.\n\nThis kit includes a new main drive belt to ensure proper fitment and function. The Rogue Engineering Power Pulley Kit is specifically designed for a range of BMW models equipped with the S54 engine, including the E46 M3 (1999-2005), Z3 M (1996-2002), and Z4 M (2003-2008).","brand":"Underdrive","offers":[{"title":"Default Title","offer_id":52689511088440,"sku":"PP.S54","price":258.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0970\/4895\/3144\/files\/687746011.jpg?v=1784907215","url":"https:\/\/store.motormia.co\/products\/pulleys-s54-engine","provider":"MOTORMIA","version":"1.0","type":"link"}
