Gday guys. Has anyone tried ruthenium spark plugs by ngk? I’ve been reading up a little bit on forums in the states, and they seem to get pretty good wraps. Probably not quite suited to a grey motor , but was wondering if anyone with performance engines has tried them. Supposed to be better ignition, longer lasting etc. Even to get a few more hp would be handy. Not sure if I should post it here or topics of other interest

Never heard of them ….

Nor I,

You wont get any noticeable horse power gains with spark plugs, they do however compliment a good ignition if they are matched appropriately.

I did an experiment with spark plugs on a dyno a few years ago, absolutely no change in HP with different brands of plugs.

The type you are talking about, is that the material their made of or just a brand name ?

Are thinking of Iridium?

There are ruthenium plugs on the market. Ruthenium is a metal element similar to platinum.
