Around 1975, General Motors made a significant advancement in stock passenger ignition technology: the High Energy Ignition (HEI). One of its major features was installation simplicity. The coil was ...
A battery in a traditional car cannot directly create engine spark. It’s only rated at 12 volts, after all, so it needs a little help boosting the signal to the spark plugs. To make that happen, a car ...
The ignition coil in C1, C2, and early C3 Corvettes is truly an amazing little device. An ignition coil is a type of pulse transformer that multiplies the low voltage received from the battery or ...
It wasn't all that long ago that GM engineers designed the original HEI system to replace the decades old points-type ignitions. In the mid-'70s, leaner mixtures demanded greater voltage and more ...
An ignition coil is a vital component of a vehicle's ignition system. It is responsible for converting the low voltage from the battery into the high voltage needed to produce sparks at the spark ...
