The Blaster SS coil from MSD Ignition is a compact design which is packed with performance. The efficient E-core windings are designed to produce high amounts of current without sacrificing the voltage output.Improves ignition spark for better engine performanceIdeal for use with MSD ignitions and other distributor based electronic ignition systemsCompact housing made from tough material for improved reliabilityTo provide the best reliability the secondary windings are wound on a segmented bobbin which reduces the chance of voltage breakdown between the primary and secondary windings. For more protection, these windings are encased in a polyurethane compound for complete protection against vibration.Supplied with a 90° boot, terminal and vibration mounts the Blaster SS coil is a perfect addition to any electronic ignition system.Specifications:Inductance: 6.9 mHMaximum voltage: 40,000 vPeak current: 300 mAPrimary resistance: 0.355 OHMsSecondary resistance: 4.4K OHMsSpark duration: 220u
