Stage 3 is built for riders who are ready to move beyond small upgrades and start chasing serious performance gains. This kit is for those who want their Spark to feel aggressive, fast, and race-inspired.
If you’ve already tasted the sharper handling and efficiency of Stage 2, Stage 3 is the natural next step, turning your ski into a craft that accelerates harder, pulls stronger through the rev range, and leaves stock skis in your wake.
Stage 3 builds on the complete handling and efficiency package of Stage 2, then adds the two upgrades that change the game: a performance-tuned impeller and an ECU tune calibrated to unlock the Spark’s true potential.
The impeller maximises pump efficiency, translating engine power directly into acceleration and top-end speed, while the ECU tune re-maps your Spark for sharper throttle response, higher output, and a more aggressive ride. Together with the upgrades from Stage 1 and Stage 2, your ski becomes more than just a Spark, it becomes a machine built for adrenaline.
Each level adds performance and control. Pick the kit that fits your needs and budget.
