There are three critical elements needed to make an engine run, air, fuel, and spark. Without one of these key items, the engine will not perform up to its full potential and could cause poor fuel mileage, low power output, and even engine damage.

The LS and LT ignition systems on GM engines are pretty good. They can go for several thousand miles without any problems while making enough spark for some decent power. The success of these factory coils does raise a question, would a better coil offer any additional gains?

The answer to this question is yes and Performance Distributors (Davis Unified Ignition) proved it with the release of their Sultans Of Spark (S.O.S.) ignition coils for the LS and now LT engines. The stock GM LS/LT coils when new can produce up to 21,000 volts while under a load. The S.O.S. coils can produce 28,000 volts under the same conditions. Meaning, the S.O.S. coils deliver 7,000 more volts under load per coil than the factory units. When we multiply this gain by eight since we have eight coils, the engine will have access to over 56,000 additional volts!

From a performance standpoint, the technology utilized in the S.O.S coils allows for a wider plug gap which will enable the engine to burn fuel more completely, ultimately leading to more power and performance. The additional energy produced will also result in quicker engine starting, smoother idle, and instantaneous throttle response where needed.

The S.O.S. coils are constructed out of a superior thermal epoxy that enhances heat transfer and vibration resistance. The coils are also designed with enhanced windings and corrosion resistant brass towers providing an excellent conduction property and conveniently mount in the OEM location.

Performance Distributors has a complete line for the ls platform and now offers new applications with the Sultans Of Spark ignition coils for the LT engine. The S.O.S. coils are available for 2016-19 Chevrolet Camaro, 2014-19 Chevrolet Corvette, 2014-19 Chevrolet Silverado 1500, 2014-19 Chevrolet Tahoe, 2014-19 GMC Sierra 1500, GMC Yukon 2014-19, and the GMC Yukon XL 2014-19.
