Denso Iridium spark plugs currently feature the world's smallest diameter centre electrode at only 0.4mm. A larger centre electrode means a greater cooling effect and poorer ignitability. On the other hand, the 0.4mm diameter iridium centre electrodes have an extremely small cooling effect, reducing non-firing and realizing assured ignitability, the basic function of a spark plug.

We currently have a wide range of Denso Spark Plugs in stock at our Sydney, Australia branch.

You can purchase them from our website by entering the spark plug number that you require in our parts search bar at:
