Performance Distributors S.O.S. Coil Packs; Square (07-13 5.3L, 6.2L Sierra 1500)Find parts that fit my vehicle

Description. Boost ignition performance with our SOS (Sultans Of Spark) Coils. These hotter coils are packed with more voltage over the stock coils to help produce increased power, better throttle response, quicker starting and smoother. The SOS coils have more volts per coil over stock and this additional spark energy will fire larger plug gaps. Extended plug gaps expose a larger spark kernel in the combustion chamber for an increased burn of the fuel mixture, thus giving your vehicle 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. Superior thermal epoxy leads to improved heat transfer and vibration resistance. Brass terminals are utilized for improved conduction and resistance to corrosion.
