What are the benefits of a CRT HEI?
Your stock ignition coil supplies only about 20,000 volts of power to the stock distributor in your Jeep. The coil used in HIGH ENERGY ignition systems puts out over 30,000 volts of usable spark energy to your spark plugs! Since you are now delivering over 30,000 volts of power to your spark plugs, you have a HOTTER SPARK. This hotter spark will burn your fuel and vapors more thoroughly, resulting in lower emissions. It will aslo consume less fuel, thus increasing gas mileage!
This "hotter spark" also causes your engine to respond better to "cold starts". You will notice far quicker engine starts even in cold weather.
That's not all...The hotter spark also creates a larger combustion in your piston chambers, therefore INCREASES YOUR HORSEPOWER AND TORQUE!
The "male" spark plug terminal posts on the HEI cap gives you a much better contact between your spark plug wires and distributor cap. Also, the spaced apart terminal posts on the HEI reduces cross-firing and thus produces a far smoother idle!
