The MSD Sport Compact Ignition is the ultimate ignition for the high revving engines that are found in smaller sport compact vehicles. At higher rpm, stock inductive ignitions cannnot produce full power sparks resulting in a loss of power or even a top end miss. The MSD Sport Compact Ignition box features capacitive discharge circuits which are capable of full power sparks at any rpm ! Whether you're idling through traffic or ripping through the gears at 10,000 rpm ,each spark of the ignition is at full power ! Full power sparks mean complete combustion which puts more power to the ground. Below 3,000 rpm, the Sport Compact Ignition box produces a series of sparks that last for 20 degrees of crankshaft rotation. This series of sparks will smooth the idle, produce quick starts and lightning quick throttle response. With this proven ignition system, your sport compact or import car will get the spark power it needs to outperform the competition on both the street and the track ! NOTE: THIS BOX IS FOR CARS WITH A DISTRIBUTOR ONLY. Will not work with distributorless ignitions.
