In the Automotive System Block Diagram, the spark plug is illustrated as the connective link to the gas engine power system.  In this respect, there are hundreds of OEM spark plugs of varied types, and with each OEM number that has been specified for specific vehicles and engines. The spark plug market is open to the prime manufacturers, and to independent spark plug manufacturers and developers.  With the independents, there are different concepts of performance improvements. However, in each case, the independent objectives are to improve over the prime manufacturers. In todays market, the objective is Power, and Mileage.  The general techniques are to alter the targeting of the spark or to increase the power of the spark.  Regardless of method, there is a deviation from the automotive engine specifications that results in a change of performance.  In any case, the limitations are in the physics of combustion, and dimensions of the engine design.

Sonic Spark Llc. has been addressing spark plug design for over twenty years.  The first patent of a Sonic Spark Plug was a spin off of an earler development that was derived from an invention of flame acoustics at Martin Marietta.  A welding nozzle whistle was designed to introduce ultra sonic vibration into the weld puddle for the fabrication of the Titan I Missle.  The addition of the welding arc added energy to the vibration which resulted in a plasma arc.  With the first energy crises, the principle was applied to fabricate an ultra sonic spark plug.  This unit worked, and exhibited significant increase of power and mileage.  However, this unit was difficult to make, and did not have any flexibility for vehicle applications.  The present Sonic Spark Plug US Patent No. 5,610,470 is universal in it applicaion.  Primarily, it is a sonic modification that is incorporated into most OEM Spark Plugs.  Thereby, it is applied to almost any gas engine type.

By using the OEM specified spark plug, Sonic Spark, Llc. stays within the design constraints of the OEM engine design.
