BMW B58 GEN1 Port injection manifold

Ready to push your B58 past the limits of the factory fuel system? This aluminum port injection manifold lets you add a second set of injectors to your B58 Gen 1, giving you the extra fuel you need for big-power builds on E85, ethanol blends or higher boost.

Why you'll love it

• More fuel, more power: port injection supplements the factory direct injection so you can run more ethanol and more boost safely.
• Aluminum construction: strong, heat-resistant and a clean look under the hood.
• Built for serious builds: ideal for upgraded-turbo, high-ethanol or track setups.

Fitment

• BMW B58 Gen 1 engines (e.g., 2016–2019 340i / 440i / M240i and other B58 Gen 1 models)
• Not compatible with B58 Gen 2 (TU) engines. 

Specs

• Material: aluminum
• Placement: front intake section

Heads up: Injectors, fuel lines and a port injection controller or compatible tune are required and sold separately. Professional installation and tuning are strongly recommended.
