When you need maximum ignition system output and reliability, the Mallory Hyfire® Ignition Control Units should be an obvious choice. The Mallory Hyfire® amplifiers provide you with the performance you need. You get more features, more power output, more accuracy, and more consistency out of a Mallory Hyfire® than comparable ignition systems.

• If you ever have been charging down the dragstrip with a competitor's ignition unit and power falls off, you need a Mallory Hyfire®.
• If you are sick of spending money of an assortment of resistor chips that fail, or you're tired of fumbling around to find one, you need a Mallory Hyfire®.
• If your ignition connections are starting to look like someone stuffed 12 power cords together into a single wall outlet, you need a Mallory Hyfire®.
• If you're sick of having to trick your ignition unit into making power with super-low resistance plug wires and huge plug gaps, you need a Mallory Hyfire®.
• If you have the common sense to realize that a manufacturer's advertising might not be 100% accurate, you need a Mallory Hyfire®.
