Finally a performance replacement coil for the popular Gen III GM small block! This engine, most notably the LS-1 and LS-6, is fast becoming a favorite performance engine. But, not just in Camaros, the new GTO and Corvettes - also in muscle cars and street rods. 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 LS-1 and LS-6 coils. Application: 1998-2002 Chevy Camaro Small block Gen III/IV (LS-based engines) 1997-2004 Chevy Corvette Small block Gen III/IV (LS-based engines)
