Bosch VT1100 Sea-Doo RXP-X RXT-X GTX GTR Fuel Injector Kit 2010–2026 – RIVA VT1100-INJK

Bosch VT1100 1100cc fuel injector kit for modified Sea-Doo watercraft. Supplied through the RIVA Racing performance range, VT1100-INJK includes three flow-matched injectors and plug-in wiring adapters for supported performance builds.

ECU calibration required: these high-flow injectors must be used with a suitable reflash or aftermarket racing ECU calibrated for the injectors and your engine setup. Plug-in adapters simplify the electrical connection; they do not remove the need for tuning.

• 3 × Bosch VT1100 fuel injectors
• Flow-matched set with 1100cc nominal injector rating
• Plug-in wiring adapters

Sea-Doo model and year guide

Selected applications span 2010–2026. Use the individual model years below, rather than assuming every model fits throughout that period. Confirm your engine modifications, fuel rail and ECU calibration before ordering.

Earlier 230 HP applications and other builds may also be supported; contact us with your exact year, model and setup to confirm. Please include your craft's year and model in the order notes.

Plan your fuel system and tuning

• MaptunerX Sea-Doo tuning bundle – confirm that an appropriate VT1100 calibration is available for your exact build before purchase.
• RIVA Sea-Doo high-flow billet fuel rail RS12050-BFR – check the rail and injector installation requirements together.
• Bosch VT1100 top-hat kit VT1100-THK – required for VT1100 installations with the RIVA billet fuel rail; sold separately.

Injector size alone does not determine horsepower. Select and calibrate the complete fuel system to suit the engine's requirements. Contact South Quay Leisure for help matching parts to your build.
