Show original supplier description
The Bosch 13518631642 is a high-pressure fuel pump (HPFP) engineered to support the performance demands of modern BMW, Mini, and Toyota Supra vehicles equipped with B46, B48, or B58 engines. By providing consistent high-pressure fuel delivery, this HDP6 pump ensures stable operation and is an essential upgrade for enthusiasts looking to utilize ethanol-blend fueling. For Gen1 B58 owners, this pump unlocks increased power potential, with reported capabilities of 525-600whp on pump gas and 450-525whp on E30 fuel. While the installation is a direct-fit process, please note that Gen1 vehicles require the use of a wire harness extension (part number CTS-WH-008), which is sold separately. Compatibility covers most B48 and B58 variants, though vehicle-specific checks are necessary. Specifically, some B46 and B48 owners in 2019 may already have an upgraded pump installed from the factory, making this unit unnecessary. Always verify your existing hardware before purchase. No ECU tuning is required for this component to function.
