Pulled the plugs this weekend and just wanted a second opinion.
Mods include Cobb SRI+TIP, Test Pipe, mild tune ... nothing serious.
I was experiencing some WOT stutter and when I pulled the IC off I noticed that recirc line from the BPV had a leak. The OEM clamp had eaten it's way through the hose and basically severed it from the nipple. Replaced the plugs and fixed the hose and car drives like a champ again. Could I stand to go to a colder plug? Looks like the plugs are very clean looking, chalky white, clean insulator. I didn't notice a lot of pitting, but one of the plugs did exhibit a small amount. My inclination is to say they are running a bit on the hot side.

I find it odd that the standard MZ3 engine calls for the same plug as the MZ3 Turbo ... and the MZ3 Turbo puts out nearly twice the power. If it's spec'ed correctly for the non turbo then it has to be on the hot side for the turbo. If it's spec'ed correctly for the turbo then it has to be too cold for the non turbo. Can't be right for both applications IMHO
