Never change points again, plus increase horsepower and improve fuel economy. Fits entirely under the distributor cap, with no “black box” to clutter the engine compartment. Installs in minutes, and is completely hidden. Other benefits: Test results show the Ignitor delivers twice the voltage to the spark plugs. No limits to coil and spark energy (spark energy is limited by the coil). A 2:1 improvement over “point type” systems in current fall time. Stable timing with no need for periodic adjustments. Increase spark plug life by 2 to 3 times. No contacts to burn, pit and corrode. No moving and rubbing parts to wear out. Better foul weather performance.
