Wagner Tuning BMW/Toyota B58 EVO1 Intake Manifold Fuel Rail Hose Kit
The Wagner Tuning B58 EVO1 Hose & Injector Kit is a fuelling upgrade designed to support multi-port injection (MPI) setups on first-generation BMW/Toyota B58 engines. This kit provides the injectors and high-quality hose assemblyrequired to complete an MPI conversion when used alongside an aftermarket intake manifold such as the Wagner EVO1 or similar.
Ideal for high-boost, hybrid-turbo and ethanol-compatible builds, this kit delivers the fuelling headroom and reliability needed to safely support increased power levels.
Key Features
-
High-flow MPI injectors suitable for tuned and high-boost B58 engines
-
Reinforced hose kit for reliable fuel delivery under increased pressure
-
Designed to integrate with aftermarket MPI-ready intake manifolds
-
Supports ethanol blends (E30–E85 depending on injector spec)
-
Improves fuelling stability and cylinder distribution at higher loads
-
Ideal for hybrid turbos, big-boost setups and advanced tuning strategies
-
Suitable for fast-road, drag and track applications
Compatibility
BMW B58 (Gen 1) Models
-
M140i (F20/F21)
-
M240i (F22/F23)
-
340i / 440i (F30/F32/F36)
-
540i / 640i (early B58 variants)
-
X3/X4 M40i (B58 Gen 1)
Toyota
-
GR Supra A90 / A91 (3.0 B58 Gen 1)
Requires an MPI-ready manifold (not included). Not suitable for B58TU/B58 Gen 2.
Ideal For
-
B58 cars running Stage 2+, hybrid turbos or ethanol blends
-
Owners adding MPI via an aftermarket manifold
-
Drivers needing improved fuelling headroom for high-boost setups
-
Supra and M Performance models used on track, drag strips or hard fast-road driving
-
Vehicles experiencing fuel pressure limitations on DI-only setups
Why Choose the Wagner Tuning EVO1 Hose & Injector Kit
As B58 power levels increase, the stock direct-injection system becomes a limiting factor — especially with ethanol mixes, hybrid turbos or aggressive boost strategies. Adding MPI solves this by supplying additional, reliable fuelling at higher loads.
Wagner’s EVO1 Hose & Injector Kit provides the essential components needed to complete an MPI conversion: high-flow injectors and a robust hose assembly designed for consistent fuel delivery. Perfect for drivers who already have an MPI-ready manifold and fuel rail, or who are building a custom setup.
This kit gives B58 tuners the flexibility, safety and headroom required for serious performance gains.
Installing / Notes
-
MUST be used with an MPI-compatible intake manifold and fuel rail
-
ECU tuning required to activate MPI correctly
-
Professional installation recommended
-
Suitable for ethanol blends depending on injector spec
