Denso Iridium plugs and gapping them.......
Im gonna treat my old saffy to some Denso Iridum racing spec plugs this weekend.
2 q's.
Firstly, anyone used them, and are they any good (theyre supposed to be...)
Secondly, what should i gap them to?? they come pre set to 1.1MM from what i remember
Oh, im also fitting a Grp A coil, so this should help give me a reasonable spark too.

Used to run Denso IK27's in my sapph, best running IK31's tho, as after extensive testing, the 31's stand upto a lot more abuse over time and are less likely to succum to core or nose damage 
As for gapping them, I never did, they came pre-gapped at 0.8mm and thats how they ran in my car (using the MSD Coilpack system aswell).
However, if you find you need to gap them, then there is a special way to do it, as the irridium nose tip is very brittle and may become damaged if gapped wrong.
