Spark Plug

KLX300R '21 - '26

E3 Resistor Spark Plugs

The unique design of the electrode maximizes the power generated by the spark plug through Diamond Fire technology. This electrode combines advanced performance capabilities and innovative technology to enhance the shape of the flame kernel. Consequently, the flame front ignites the air/fuel mixture more rapidly, accelerates heat transfer into the combustion chamber, and creates a more concentrated pressure front, facilitating a quicker pressure rise during the cylinder power stroke. The outcome is a more efficient combustion process and improved engine performance, making this a truly premium spark plug.
