The right spark plug for peak performance

Today's spark plugs are designed for a wide variety of functions and applications, yet they all serve a common purpose: to ignite the engine's air-fuel mixture and remove heat from the combustion chamber. Automotive racing powerplants run at varying temperatures due to the types of fuel they burn, which in the final analysis may dictate which type of plug offers peak performance.

Spark plugs transmit electrical energy that turns fuel into working energy. When the ignition is triggered, the spark moves through the rotor, to the cap, down the wire into the spark plug, and it jumps the gap of the spark plug, creating a spark kernel that ignites the air/fuel mixture in the combustion chamber.
