  • MSD Ignition 690 Details

    Note: Legal only for off-highway use (except in California or states that have adopted California emission standards), racing use or for use on pre-emission-controlled motor vehicles/motor vehicle engines (pre-1966 domestic vehicles certified to California standards, pre-1968 domestic vehicles certified to federal standards and all pre-1968 foreign vehicles), per the manufacturer’s application guide.

    This MSD/Mallory HyFire Ignition Control Box is engineered with modern capacitive discharge technology that delivers powerful performance results. The capacitive discharge of the HyFire Ignition produces multiple sparks at low rpms, resulting in improved starting, clean idle and quick throttle response. A built-in adjustable rev limiter adjusts in 100 rpm increments to prevent a missed shift or driveline failure. This retro-designed HyFire ignition Box has good looks and easily connects to points, amplifiers and magnetic pickup distributors.
