{"product_id":"fx-180-high-pressure-fuel-pump-1","title":"FX-180 High-Pressure Fuel Pump","description":"The Spool Performance FX-180 is an upgraded high-pressure fuel pump engineered for the BMW B58 engine. This pump significantly increases fuel flow by approximately 80% compared to the stock unit, thanks to its larger bore size. It is fully compatible with E85 fuel, enabling enthusiasts to run higher ethanol blends and support more aggressive tuning.\n\nThe stock high-pressure fuel pump (HPFP) on B58 motors can become a limitation when attempting to tune for increased output. The FX-180 addresses this by raising the fueling limits of the platform, providing the necessary fuel volume for larger turbocharger applications and higher ethanol concentrations. Flow rates are approximately 1.7 cc per rev for the FX-180, compared to the stock B58 pump's 0.954 cc per rev, based on stock CAM lift.\n\nIt is important to note that tune changes are required to utilize the full potential of the FX-180 system. These calibration adjustments are available from major tuning companies, and Spool Performance can provide the necessary changes upon request. This fuel pump upgrade is specifically designed for various BMW B58 engine applications, including models like the M140i, M240i, 340i, and 440i across different chassis codes and production years from approximately 2015 to 2019.","brand":"Spool Performance","offers":[{"title":"Default Title","offer_id":52866388427064,"sku":"SP-FX-180-B58","price":1899.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0970\/4895\/3144\/files\/687688482.jpg?v=1787907021","url":"https:\/\/store.motormia.co\/products\/fx-180-high-pressure-fuel-pump-1","provider":"MOTORMIA","version":"1.0","type":"link"}
