{"product_id":"high-pressure-fuel-pump-for-bmw-b58","title":"High-Pressure Fuel Pump for BMW B58","description":"The Spool Performance FX-180 is an upgraded high-pressure fuel pump (HPFP) engineered for the BMW B58 engine. This Stage 1 upgrade boasts a significantly larger bore size, delivering roughly 100% more flow than the factory pump. This enhanced flow capacity is crucial for enthusiasts looking to run higher ethanol concentrations, such as E85, and to adequately fuel larger aftermarket turbochargers.\n\nHowever, it is essential to note that the upgraded pump necessitates calibration changes. These changes must be applied before starting the engine with the new pump installed to prevent potential damage and to avoid voiding the warranty. Spool Performance offers support by providing calibration details to tuners or connecting customers with experienced tuning professionals. Custom tuning is ultimately required to maximize the performance gains of the upgraded pump based on specific vehicle setups and conditions.\n\nProper low-pressure fuel system performance is critical for the longevity and correct operation of high-pressure pumps and injectors in direct injection systems. Inadequate low-pressure fueling can lead to damage, which may be detectable and void warranties. It is strongly recommended to plan for necessary low-pressure fuel system upgrades concurrently.\n\nImportant compatibility notes: This pump is NOT compatible with the B58TU engine. Additionally, this product is not for sale or use in the state of California on any pollution-controlled vehicle, as per California Air Resources Board regulations.","brand":"Spool Performance","offers":[{"title":"Default Title","offer_id":52689715757368,"sku":"FX-180","price":1799.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0970\/4895\/3144\/files\/687754914.jpg?v=1784909476","url":"https:\/\/store.motormia.co\/products\/high-pressure-fuel-pump-for-bmw-b58","provider":"MOTORMIA","version":"1.0","type":"link"}
