The design aims to improve ignition speed and burn efficiency, which can help with issues like poor idle, power loss, or bad fuel economy. Installation is pretty straightforward—plug and play. Keep your outboard running smoothly and extend its life. A must-have for any boat owner doing their own maintenance. Always double-check your model year to ensure compatibility.
