B58 Gen 1 Upgraded Direct Injectors

Upgrade your B58 Gen 1 engine's fuel system with the MODE Auto Concepts Upgraded Direct Injectors, designed to push performance boundaries without the need for port injection systems. These injectors are available in two stages: Stage 1 offers a 35% increase over stock flow (14.1 g/s at 100 bar), supporting up to 780 WHP on gasoline or 630 WHP on E85. Stage 2 provides an even greater 66% increase over stock flow (17.3 g/s at 100 bar), capable of supporting up to 880 WHP on gasoline or 700 WHP on E85. They operate seamlessly with the OEM ECU's engine management system, preserving all diagnostic and safety functions for a more responsive and reliable system. Precision Raceworks ensures quality through static and dynamic testing of every injector, guaranteeing optimal performance and consistent batching. The product includes comprehensive installation instructions and is backed by a limited lifetime warranty. It is crucial to note that these injectors are specifically for the Gen 1 B58 engine. They are not compatible with the Gen 2 B58 engine, which utilizes a higher pressure fuel system (450 bar vs. the Gen 1's 250 bar system). A tune is required for proper operation with these upgraded injectors. The manufacturer emphasizes the importance of an OEM equivalent spray pattern to prevent issues such as poor idle quality, drivability problems, increased knock propensity, soot, NVH, and tuning difficulties. An improper spray pattern can also lead to fuel impinging on cylinder walls, causing oil dilution and increased mechanical wear. These injectors are compatible with a range of BMW models including the 340i, 340i xDrive, 440i, 440i xDrive, 540i, 540i xDrive, 640i xDrive, 740i, 740i xDrive, M240i, M240i xDrive, X3 M40i xDrive, and X4 M40i xDrive, generally from model years 2016 to 2021, depending on the specific vehicle.
