XDI parts sit in three groups: high-pressure fuel pumps (HPFP 35, EVO and 60), direct injector sets, and the 5500 psi soft line for the Civic Type R. Compare other brands in Fuel Pumps, Fuel Injectors and Fuel Line Kits.

XDI hardware is model and chassis specific, so match your selection to the chassis code and engine family stamped on your vehicle:

• Honda Civic Type R (FK8/FL5): HPFP EVO, HPFP 60, direct injectors and the 5500 psi direct injection soft line.
• Ford Focus ST (LW/LZ) and Focus RS (LZ): HPFP 35, HPFP 60, HPFP EVO and direct injector sets.
• Ford Mustang 2.3 EcoBoost (S550): HPFP upgrade and direct injectors.
• BMW B58 (G20/G21) and Toyota GR Supra (A90/A91): high-flow direct injectors.
• BMW S58 (G87 M2, G80 M3, G82 M4): S58 +30% direct injectors.
• Mercedes-AMG A45 (W176), CLA45 (C117), GLA45 (X156), M133 engine: high-pressure fuel pump.

Pumps are described by XDI as offering up to 60% more flow than factory units, which supports safe air-fuel ratios at higher boost and suits high ethanol blends such as E85 while retaining the atomisation and charge cooling benefits of direct injection.

XDI pumps are designed as OEM-plus bolt-on upgrades for platforms such as the Civic Type R (FK8/FL5) and Ford Focus RS/ST, with no additional wiring or external controllers required. Because the pumps move significantly more fuel per stroke than the factory unit, a custom ECU calibration on a supported platform such as Hondata, MoTeC, Bootmod3 or MHD is required.

You will also need appropriate high-pressure fuel line hardware, fresh sealing components where specified by the manufacturer, and correct fuel system depressurisation procedures. Installation by a professional is recommended, with tuning by a qualified tuner.

Where can I buy XDI fuel pumps in Australia?

Chicane Australia carries XDI high-pressure fuel pumps, direct injectors and fuel lines and ships Australia-wide from the NSW Central Coast. Shop by vehicle above, search by XDI part number, or contact our team with your engine and tune platform.

Why choose XDI over a port injection kit?

XDI allows the vehicle to remain 100% direct injection. Port injection requires secondary fuel rails, extra wiring and a separate controller, which adds further points of failure. Upgrading the DI system with an XDI pump and injectors retains factory OBD diagnostics and the fuel atomisation characteristics of direct injection.

Is a tune required for XDI fuel pumps?

Yes. XDI pumps move significantly more fuel per stroke than the factory unit, so a custom ECU calibration is mandatory. Platforms such as Hondata for the Civic Type R, or Bootmod3 and MHD for BMW, include specific settings to support XDI hardware.

Are XDI products suitable for E85?

Yes. The added flow capacity of XDI pumps and injectors is intended to support high ethanol blends such as E85, where fuel demand is considerably higher than on pump petrol.
