NEW SPARK PLUG UPGRADE ON ROCKET3R

DPR8EIX-9 and I put a dab of anti seize on the plugs when installing. 05 and 2013

Avoid Iridium plugs because they have much higher resistance and require higher electrical output than the stock Rocket III (2.3L) can produce to perform as well as the standard plug on our Rockets. That is why Triumph does not use them. Now if you can up grade your electric output to the ignition system, Iridium plugs may actually be better in the Rocket. But not in a bone stock Rocket III (2.3L).

Good to know, thank you.

Sorry Idaho Red, but I do not think iridium plugs take any more to make a spark, than most any other plug. The only part of an iridium spark plug that is iridium, is the electrode, which is the part that wears away on other spark plugs. In the old days, and maybe still, they used to make "resistor" spark plugs, that indeed took a little more umph to get through the resistor that was built into the spark plug. Also some plug wires have resistance built in, both mainly do reduce radio interference.

"From the linked article"
Spark plugs play an essential role in gas ignition engines by generating an electric spark across a small ignition gap, that fires a combustion chamber and powers the engine. There are three types of spark plug – iridium, platinum/rhodium, and copper – and all work in the same way, so talking about the difference between iridium and ‘normal’ spark plugs is somewhat misleading. The only real difference is the metal used to create the central electrode.

There are three types of spark plug – iridium, platinum/rhodium, and copper – and all work in the same way, so what makes them different?

the chart I posted for replacement Iridium spark plugs have exact same resistance as stock rocket spark plugs currently coming from triumph.

I am not sure what you meant by different resistance on iridium spark plugs.

I'm speaking of the original 2.3L Rocket III.
