have fitted ngk iridium plugs in the past on my blade and have them on the cb1300 cannot say if they make a noticable difference to the bike but they claim the service life is longer than ordinary plugs and they give a better spark and improved combustion etc unsure if they are worth the extra cost though

Using Iridium plugs on my Triarm and my 400/4, got to be worth the extra for the extended service life & benefits, changing plugs on a Triarm aint a 10 minute job...

Don't know, never been out on my bike with stock plugs lol
My bike runs fine tho with the plugs and that's the most important thing for me lol

I run Iridium NGKs in both my GSXRs as got a box of them cheap in the US years ago, less than normal plugs here

Found them to give improved starting and idling but that's it.

Standard plugs.

Denso ones.

I use whatever is the cheapest but the last two batches of NGK's ive had have had duff plugs in them so back to Denso.
