Features & Benefits Our performance ignition modules are direct replacements for popular GM and Ford electronic distributors. These modules provide enhanced high RPM performance and when used with their corresponding Flame-Thrower coil, substantially increase spark plug voltage. Thick film technology on alumina ceramic substrates removes heat for greater accuracy and improved reliability. Laser trimming gives precise peak current control for increased energy output.
