Description
Experience the next generation of direct injection with the Dorch Engineering DE70 Injectors — the world’s first true aftermarket upgraded DI injectors for the BMW B58 Gen1 engine. Developed from the ground up in collaboration with Tier 1 OEM supplier Stanadyne, the DE70 injectors are not modified stock parts, but purpose-built to deliver massive fuel flow while maintaining factory drivability and idle quality — even on ethanol fuels like E85.
Thanks to a highly efficient magnetic design and precision spray control, these injectors provide +70% more fuel flow than stock without the compromises of traditional modified injectors. Expect flow capacities supporting up to 1050whp on pump gas, 900whp on E50, and 800whp on E85, depending on tuning. The DE70s are plug-and-play and are backed by Dorch's lifetime warranty.
Unlike anything currently on the market, these injectors feature improved internal materials for optimal E85 compatibility, enhanced low pulse-width control, and precise OEM-level batching and calibration. Whether you’re building a street monster or a track weapon, these injectors are the ultimate fueling solution for high-performance Gen1 B58 applications.
