Denso iridium sparkplugs

[Volvi]

Has anyone tried these plugs for the Busa? and if so can you report on them.

I have asked this before but it got lost in all the flak that was about at the time....

Haven't stuck a set in the 'bus yet, but I used them on my CBR1000 successfully. Got more mileage, seemed to pull a bit harder and was certainly smoother. Never needed the choke again either - even in mid winter up in the Dandenongs.

I have them in now and the same results as BigMac.
Also, a little sharper at low revs. I know this, coz I put them in before anything else ie. filter, PC2, ....
