Do you want quicker acceleration, faster planing, and increased performance of up to 15 HP? If so, the "SS" Super Sport tuning kit for your MerCruiser Magnum MPI engine is what you need. This kit includes the "SS" Sport Series flame arrestor that utilizes a clamp-on style K&N element with our high velocity style air inlet.

This kit also comes with an adjustable billet Flow Command fuel pressure regulator that allows you to tune your air fuel mixture for optimum performance.

NOTE: You will need to send us your ECU with this questionnaire for re-calibration.
