{"product_id":"hdp6-high-pressure-fuel-pump-2","title":"HDP6 High-Pressure Fuel Pump","description":"The Bosch 0261520520 is a genuine Bosch HDP6 high-pressure fuel pump (HPFP) that serves as both a direct replacement and a performance upgrade for B46, B48, and B58 engines. This pump offers increased fueling capabilities, with a flow rate of 1.178 cc\/rev and a maximum pressure of 350 bar, compared to the stock HDP-5-EVO pump's 0.954 cc\/rev and 250 bar.\n\nFor Gen 1 B58 owners, this HPFP is a crucial upgrade, capable of supporting 525-600 whp on pump gas and 450-525 whp on E30 fuel blends. Owners of B46\/B48 engines manufactured up to 2019 will also see benefits; however, it's advised to check if the 2019 models already have the upgraded pump installed. This pump is compatible with most BMW, Mini, and Toyota Supra B48\/B58 variants.\n\nInstallation on Gen 1 B58\/B48 engines requires a wire harness extension (CTS-WH-008), sold separately. While no tuning is strictly required for basic operation, tuning is necessary to achieve maximum performance gains. For Gen 1 B58\/B48 installations, the connector housing for the fuel quantity control valve may need to be rotated, a process described as straightforward. Alternatively, an extension harness can be used, though it is not essential as the connector can be rotated.\n\nFailure of a direct injection high-pressure fuel pump can lead to various drivability issues, including hard starting, hesitation, misfires, loss of power under load, check engine lights, and lean\/rich codes. This Bosch HPFP is engineered in Germany to OE specifications, ensuring quality and reliability.","brand":"Bosch","offers":[{"title":"Default Title","offer_id":52687245738296,"sku":"0261520520","price":741.6,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0970\/4895\/3144\/files\/660189330.jpg?v=1784881797","url":"https:\/\/store.motormia.co\/products\/hdp6-high-pressure-fuel-pump-2","provider":"MOTORMIA","version":"1.0","type":"link"}
