Spark Plug

CRF150R '07 - '18

Iridium spark plugs are made with premium quality materials.

Iridium plugs last longer than standard ones, meaning you won't have to replace them as often.

  • The ultimate in the evolution of spark plug technology and performance from an industry leader
  • The iridium electrode is 25% smaller than a platinum electrode, and it's just 1/4 the size of a conventional nickel electrode
  • Ultra-small diameter center electrode reduces voltage requirement and extends ignition system life
  • Metal shell plating has enhanced anti corrosion qualities

Sold individually, unless otherwise stated.

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.
