Don't let the compact size of the ProMaster S/S Coil fool you. The efficient E-core windings are designed to produce high amounts of current without sacrificing voltage output. In fact, when used with a Mallory HyFire Ignition, the ProMaster S/S produces 300 milliamps of current and a maximum voltage output of 40,000 volts! The ProMaster S/S features brass terminals and a sturdy housing for long life, durability and maximum performance. It is supplied with a 90° spark plug boot, terminal and vibration mounts. It's a great addition to CD Ignitions and some stock applications.
