Electronic Distributors are distributors that have upgraded from the old points system. Distributors create the electricity needed to pass through your ignition leads to the spark plug that ignites the fuel entering into the chamber. The primary advantage offered by an electronic ignition that is circuit-based instead of mechanically-controlled is in how the electrical impulse is distributed to the spark plugs. Utilizing transistors, sensors, and electrical switches, such as the thyristor, to control electrical flow is more accurate, reliable, and durable than a breaker-point system controlled by a mechanically-rotating distributor head. Since it is highly precise, this also prevents incomplete combustion of fuel in the piston chamber of an engine, leading to better fuel efficiency and reducing pollution. T's & C's Apply
