These Iridium spark plugs are they really worth all that extra expense?
Does anyone have any views on these highly expensive babies,

I think they are OK. I bought some NGK iridiums for about the same price at their platinums (about £7 ea I think).

Nice thing about iridium's are they should last 60k miles, opposed to platinum, which seem to wear out after 30k.... and you will notice a slight performance improvement, too.

As this could be 6-7 years of typical motoring, do they (can they?) need to be re-gapped or taken out for checking?
