Now available is our new line of SOS (Sultans Of Spark) Coils for the 1997-2013 General Motors LS/VORTEC engines. These hot new coils are packed with additional voltage over the stock coils to help produce more power, better throttle response, quicker starting and smoother idle! The new LS SOS Coils have 7000 more volts per coil to be exact and this additional spark energy will fire plug gaps up to .065″. Larger plug gaps expose more spark in the combustion chamber for an increased burn of the fuel mixture thus giving your LS extra performance and better fuel efficiency. Our design team has used the latest technology to enhance the coil windings for higher output, yet maintained the original size so the coils will mount in the oem bracket and retain the factory wiring. LS SOS Coils are fully compatible with flash devices and programmers. Superior thermal epoxy leads to improved heat transfer and vibration resistance. Brass terminals are utiltized for improved conduction and resistance to corrosion. LS SOS Coils have a one year warranty from date of purchase.
