Has anyone ever tried the new NGK Ruthenium spark plugs (LKAR8BHX)? They're going for $68 for a set of 6 over at Zspeed. Searched the forum and only found 2 posts about it and nothing much else on the interwebs on how they perform on VQ platform.

I'm deciding between the NGK Ruthenium and the Iridiums DF8H-11B. Have some trust issues with Denso.

Stock 370z with roughly 60k miles on the clock.
