The Blaster high vibration ignition coil from MSD ignition is an ideal upgrade to your stock coil, or to compliment the performance of your MSD Blaster 6 Ignition. The coil internals are completely potted in a premium grade epoxy to protect them from vibrations making this coil perfect for competition use. The Blaster Coils are designed for improved spark output with special 100:1 windings to provide maximum build up of voltage for optimum performance.Ideal for high vibration applications such as MotorsportsImproves ignition spark and engine performanceSuitable for electronic ignition and MSD ignition systemsThe MSD ignition blaster high vibration coil is suitable for use with single coil based electronic ignition and MSD ignition systems. They can also be used with a contact breaker ignition system but a separate ballast resistor would need to be fitted.Specifications:Inductance: 8 mHMaximum voltage: 45,000 vPeak current: 140 mAPrimary resistance: 0.7 OHMsSecondary resistance: 4.5K OH
