With DENSO's very own U-Groove ground electrode for better spark performance

To increase ignitability, the important point is to let the flame kernel caused by the spark to grow to a large size. Normally, this can be accomplishing by widening the spark gap, however this causes spark voltage to increase, which has the opposite effect. IRIDIUM POWER uses DENSO very own U-Groove ground electrode to realise a superb ignitability while maintaining spark voltage at low levels.

Comes in 4 pieces - IK16 / IK20 / IKH16 / IKH20
