Multiple sparks at idle rpmDirect bolt-in to factory connectorsImproved spark energy and voltage outputPatented winding design and materialsMSD's engineering team have been working diligently the past year to improve our Multiple Spark Coils for the GM LS-engine platform. The new coils fit in place of the OEM coils yet are capable of delivering higher spark energy to the plugs, topped with multiple sparks at idle rpm. Increased spark energy and voltage, along with multiple spark capabilities, help improve the combustion process of the fuel mixture to create an efficient burn. This results in improved throttle response, smooth idle and quick starts, plus increased high rpm perfor
