Finally a performance replacement coil for the popular Gen III GM small block! This engine, most notably the LQ Truck / LS6 and now the new LS2, LS7 series is fast becoming a favorite performance engine. But, not just in Camaro's, the new GTO and Corvettes - also in muscle cars, trucks and SUV's.
The complex electronic controls of the original coils presented the aftermarket with a challenge as the drivers that control the firing of the coils are built into the OE models. MSD engineers were able to design an advanced circuit that will operate with the factory electronics of the Gen III engine controls while producing a higher output spark. Not only do you get a higher voltage spark, but the coil will deliver multiple sparks! That’s right - multiple spark discharge coils!
Notice that the coil has two connectors molded into the custom housing. One accepts the factory coil connector, the other is for an upcoming ignition controller. (This controller is still in the development stages but it will allow you to program functions of the ignition. We’re planning a lot more for the Gen III fans!) The new coils mount in place of most factory LS1 / LS2 / LQTruck / LS6 / LS7 coils. All installation hardware included.
MSC II Multiple Spark Coils feature:
- Direct replacement multiple sparking coils for GM Gen III engines.
- Advanced circuitry produces three times the spark energy of stock coils.
- Direct bolt-in design accepts factory wiring harnesses.
- Complete kit with mounting hardware for easy installation.
