The Flame-Thrower II is a high-performance 12-volt coil that is perfectly matched to the Pertronix Ignitor II breakerless ignition. The epoxy-filled coil supports the internal windings better than oil for resistance to high vibration use. The 0.6 ohm primary resistance is designed to work with the Ignitor II as well as some stock electronic and CD ignition systems. Standard round cannister retains a "stock" look and fits common coil mounting brackets. Black only.
