Denso 5304 Spark Plug
Denso Iridium Spark Plugs are designed to ignite the air-fuel mixture in the engine cylinder by generating sparks between the center electrode and earth electrode. They employ an iridium alloy for the center electrodes and provide superb ignition performance. These plugs have lower fuel consumption and higher acceleration performance as well as stable combustion during idling, which contribute to the cleaner exhaust.
