Product Description

The Wagner Tuning B58 EVO1 Hose & Injector Kit is a fuelling upgrade designed to support multi-port injection setups on first-generation BMW and Toyota B58 engines.

Designed to work alongside an MPI-ready intake manifold such as the Wagner EVO1 or similar, this kit provides the high-flow injectors and reinforced hose assembly required to complete an MPI conversion.

As B58 power levels increase, especially with Stage 2+, hybrid turbo and ethanol-compatible builds, the factory direct-injection system can become a limitation. Adding MPI provides additional fuelling headroom, improved fuelling stability and more reliable fuel delivery at higher loads.

Suitable for fast-road, drag and track applications, this kit is ideal for tuners and enthusiasts building higher-power B58 setups that require safer, more consistent fuelling support.

FAQs

What does the Wagner Tuning B58 EVO1 Hose & Injector Kit do?

It provides the injectors and reinforced hose assembly required to support a multi-port injection conversion on compatible B58 Gen 1 engines.

Which engine is this kit designed for?

It is designed for first-generation BMW and Toyota B58 engines.

Does this kit fit B58TU or Gen 2 engines?

No. The supplied information states that it is not suitable for B58TU / B58 Gen 2 engines.

Which vehicles does it fit?

It is listed for B58 Gen 1 BMW M140i, M240i, 340i, 440i, early 540i / 640i, X3 M40i, X4 M40i and Toyota GR Supra A90 / A91 3.0 models.

What is MPI?

MPI stands for multi-port injection. It adds additional fuel injection through the intake manifold to support higher power levels beyond the factory direct-injection system.

Does this kit include injectors?

Yes. The supplied information states that high-flow MPI injectors are included.

Does this kit include the hose assembly?

Yes. It includes a reinforced hose kit for reliable fuel delivery.

Does this include an intake manifold?

No. An MPI-ready intake manifold is required but not included.

Does this include a fuel rail?

The supplied information states that the kit must be used with an MPI-compatible intake manifold and fuel rail, so fuel rail inclusion should be confirmed separately unless specified.

Is ECU tuning required?

Yes. ECU tuning is required to activate MPI correctly.

Is this suitable for ethanol blends?

Yes. It can support ethanol blends such as E30–E85 depending on injector specification.

Is it suitable for hybrid turbo builds?

Yes. It is ideal for hybrid turbo, big-boost and high-power B58 applications.

Is it suitable for track or drag use?

Yes. It is suitable for fast-road, drag and track applications.

Why add MPI to a B58?

As power levels increase, especially with ethanol, hybrid turbos or aggressive boost strategies, the factory direct-injection system can become a limitation. MPI adds extra fuelling capacity and stability.

Is professional installation recommended?

Yes. Professional installation is recommended.

What should I check before ordering?

Please confirm your exact vehicle model, B58 generation, MPI-ready manifold and fuel rail setup, injector specification, tuning strategy and ethanol requirements before ordering.
