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.
