PRODUCT DESCRIPTION
FMIC.EU Port Injection Kit for BMW B58 M240i 340i 440i 2015-2023
The FMIC.EU fuel injector mounting adapter for BMW B58 engines is an essential modification for those planning to increase power, use E85, increase turbo pressure, or install a larger turbocharger. While the B58 engine's factory direct injection system is efficient, it becomes a limitation at high power levels; port injection effectively solves this problem.
The kit allows for additional and evenly distributed fuel delivery to each cylinder, ensuring better combustion and stable engine operation even under very high loads. Its design integrates perfectly with the vehicle as a factory component; once installed, the kit is practically invisible.
The FMIC.EU port injection kit is made of precision CNC machined aluminum, is fully compatible with E85 fuel, and is ready for use in high-performance street and track builds.
Features and Benefits: - Precision CNC machined plate: perfect fit between the intake manifold and the cylinder head - Even fuel distribution to all 6 cylinders - E85 compatible, 100% ethanol resistant - 6 injection ports, compatible with aftermarket injectors
Kit contents: - 1 injection plate - 1 fuel rail - 6 OEM style gaskets - 9 screws and washers
Recommended modifications: - Fuel injectors: 550 cc / 750 cc / 1000 cc - Upgraded Low Pressure Fuel Pump (LPFP), especially for E85 - ECU retuning for the new fuel configuration
