AEM Twin-Fire Ignition Module 4 Channel CDI 30-2821
Description
Notes: This is a discontinued AEM item and is 100% NEW IN THE BOX. AEM does not make these anymore. This may be the last new stock for this item in existence.This is an ignition amplifier that you use when your car starts to blow the spark out and you need a more powerful ignition.
A lot of cars will start to run out of spark energy as you start to make more power. There is really nothing you can do to cure this problem except for increase the strength of your ignition system. That is exactly what an ignition amplifier is for.
This particular ignition amplifier works really well and is a lot more affordable than other ignition amplifiers on the market.
WHAT IT DOES
AEM’s 4 Channel digital multi-channel Twin-Fire Ignition is a multiple-spark twin-capacitive discharge ignition system. The Twin Fire ignition delivers full energy to the spark plug at engine speeds exceeding 10,000 RPM, regardless of the time between ignition events, ensuring that pressurized fuel mixtures are thoroughly ignited. Standard inductive ignition systems typically produce around 250 volts on the coil primary. The Twin Fire's capacitive discharge ignition (CDI) produces a fast, high energy pulse that is applied to the ignition coil that is over 500 volts. This higher primary voltage is what allows the Twin Fire to produce a much higher spark voltage. A typical ignition coil (1:100 turns ratio) with an inductive ignition will produce about 25,000 volts to the spark plug, but using the Twin Fire with the same coil will produce 50,000 volts or more at the spark plug.
WHY YOU WANT ONE
If you have either a high compression, high boost, high RPM or a high horsepower car that demands a lot of spark energy, the AEM Twin Fire is an ideal solution for your ignition system needs.
