Denso Iridium Spark Plug IK22

Denso Iridium Spark Plugs feature the world's smallest center electrode, measuring 0.4mm in diameter. Because the majority of spark is exposed to the air/fuel instead of the metal surface, the fuel burn is greater (0.5 increase over platinum), which ultimately improves gas mileage.

Price is for one.
