Fuel-It! Port Injection Kit — S58 (G8x M3/M4, G87 M2, X3 M / X4 M)

$1,995.00

Fuel-It! port injection kit for the S58 — the G8x M3/M4 (including M3 Touring and M4 Convertible), G87 M2, and F97 X3 M / F98 X4 M. Low-pressure port injection across all six intake runners, backing up the S58's direct injection for big power on pump, race gas, or E85 (Fuel-It rates the kit up to 1,000+ whp with the right injectors).

What it is

A Fuel-It S58 billet fuel rail, up to six flow-matched port injectors (sized to your choice), stainless-braided lines, a port-injection controller, and the install hardware/jig. It supplements the factory DI; injector size sets the power ceiling.

Options

Three choices in the configurator. Injector: No injectors (rail and hardware only, to carry over your own set), or 550, 750, 950, or 1050cc — size it to your power target. Controller: Standard fires the port injectors as a batched bank; CANfuel Sequential is Fuel-It's CAN-bus controller that fires each injector in sequence with the engine for finer fuel control. Flex-Fuel: None, reuse your existing flex-fuel sensor, or add a new sensor.

Where it fits in the build

Supplemental fuel for high-power S58 builds. We tune the engine to the fuel system.

Fitment

S58 — G80 M3, G81 M3 Touring, G82 M4, G83 M4 Convertible, G87 M2, F97 X3 M, F98 X4 M. Confirm your chassis in the selector.

WHY WE SHIP FUEL-IT!
Fuel-It! builds the LPFP and HPFP upgrades and the flex-fuel sensing kits that make running ethanol a clean, repeatable thing instead of a guess. Their ethanol-content sensing lets a calibration read actual blend in real time and adjust, which is what makes a flex-fuel build safe to daily. We use Fuel-It! parts where a customer wants the gains ethanol gives but needs the fuel system and the sensing to handle a tank that is never quite the same mix twice. It is the bridge between pump-gas reliability and the bigger numbers E-blends make possible.
