Well I'm glad someone has had a lash at these plugs........I have been wondering for months wether they are any good.......but like most people , at around $80 a set

they would want to be a *whole* lot better than your common-or-garden platinum plugs
$20 bucks per plug ?? ..........hmmm, I must tell a related 'plug' story.....
back in 1981, when you could buy a set of 6 NGK plugs for your Holden Red 6 for about 6 bucks.........there was a spark-plug called the 'Golden Lodge' - standard equipment in Lambos, Ferraris, etc. It had 4 earths around the electrode, and didn't need gapping.
Thes plugs were $6 EACH FFS !!!! $24 f'n dollars for a 4 cyl bike

it was unheard of , and considered an outlandish expense.........so I got a set

, and bugger me, the bike ( this was the EFI Zed.)....immediately idled better, and pulled through the gears better. I have never forgotten this, it was really quite strange to consider that a sparkplug could be a *performance* accesory.......
history just keeps repeating

Aussie Ninja, you have convinced me to get a set of these and see for myself........
well bugger me - I just had a look at the site

these are the 'Golden Lodge' of the new Millenium !!!!!!!!!!!
