Description
Designed specifically for BMW’s high-precision Gasoline Direct Injection (GDI/HDEV) systems, including N20, N55, B48, and B58 engine platforms, this Bosch fuel injector delivers ultra-precise fuel metering and multi-hole high-pressure atomization. Built to match rigorous Original Equipment (OE) standards, it ensures instant fuel-air mixing, maximizes combustion efficiency, and maintains sharp throttle response under high boost and RPM conditions. Engineered with anti-clogging micro-passages and superior thermal stability, this component eliminates misfires, uneven idling, and fuel dilution. It serves as a premium replacement solution for wholesale auto parts distributors, BMW performance specialists, and European repair networks worldwide.
Technical Parameters
| Category | Specifications & Technical Details |
| Structural Design | High-pressure solenoid suspended-drive architecture integrating a built-in micron-level fuel inlet filter screen, high-sensitivity solenoid coil, precision needle valve assembly, and multi-hole precision micro-jet nozzle plate. |
| Core Material | Constructed with carburized high-permeability wear-resistant alloy steel, austenitic stainless steel housing, and FKM / Viton O-ring seals resistant to high-temperature and high-pressure fuel corrosion. |
| Energy Transmission | High-pressure direct liquid pulse spray transmission — controlled by ECU solenoid pulse signals to achieve millisecond-level high-frequency precise opening and closing. |
| Circuit & Insulation System | Low-impedance high-pressure solenoid circuit design with dielectric withstand strength exceeding 500V DC. Built-in high electromagnetic compatibility (EMC) anti-interference components ensure precise signal synchronization with BMW DME (Digital Motor Electronics) engine control units. |
| Protection & Durability | Capable of withstanding fuel rail pressures up to 150–350 bar. Excellent resistance to coking and ethanol-blended fuels (E10 / E85). Stable operation in extreme in-cylinder environments from -40°C to +150°C. |
Applicable Car Brands & Models
Common symptoms include engine misfiring (DTC codes P0300–P0306), rough or unstable idling, hesitation during acceleration, increased fuel consumption, strong gasoline odors in the exhaust or engine oil, and an active Check Engine Light (CEL/Drive Moderately warning).
Yes, Bosch is a primary Original Equipment Manufacturer (OEM) for BMW. Bosch GDI injectors are manufactured strictly according to BMW factory physical dimensions, coil resistance, and flow rate parameters, ensuring 100% direct plug-and-play fitment.
For most modern BMW GDI engines (such as N20, N55, B48, and B58), individual injector calibration values (flow rate/compensation codes) printed on the injector body must be programmed into the DME via a diagnostic tool to ensure smooth cylinder balance.
The Minimum Order Quantity (MOQ) depends on specific SKU inventory. For fast-moving Bosch SKUs in stock, the MOQ starts as low as 10–20 units (or in engine sets of 4/6). Typical lead times are 3–5 business days for stock items and 15–30 days for bulk factory orders.
