Always check the gap before you install them.

Start at 0.7mm and see how it goes...

I have IK31, and ran them at 0.65mm with a group a coil, but as said experiment a bit.

didnt think you were suposed to gap the iridiums, because the tips are brittle?

Can't think they can be that brittle with the environment they work in.
I have always gapped then without problem.
