Set of 8 VMS PRO SERIES RACING REPLACEMENT Multiple Spark Coils that will fit in place of the stock GM LS coils and will directly connect to the factory connectors. These coils will deliver improved power and performance because of the higher energy output.
Increased spark energy and voltage, along with the low RPM multiple spark capabilities, help improve the combustion process of the fuel mixture to create an efficient burn. The result are quicker starts, improved idle, improved throttle response , cleaner plugs, cleaner emissions plus increased high rpm performance!
