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
