What is HEI ignition?

High Energy Ignition (HEI) is an ignition system that was developed by General Motors in the late 1970s. It was designed to improve the performance and reliability of gasoline engines by providing a more powerful spark. HEI systems use a special ignition coil and distributor that are designed to work together to produce a higher voltage spark. This spark is more effective at igniting the fuel mixture in the engine, which can result in improved engine performance and fuel economy.

HEI systems are typically used in high-performance engines, but they can also be used in standard passenger vehicles. They are a popular choice for people who are looking for a way to improve the performance of their engine without having to make any major modifications.

Here are some of the benefits of HEI ignition systems:

* Improved engine performance

* Increased fuel economy

* More reliable engine starting

* Reduced emissions

* Smoother engine operation

If you are looking for a way to improve the performance of your engine, an HEI ignition system is a great option. It is a relatively simple and inexpensive upgrade that can make a big difference in the way your engine performs.
