Cheers Hazz. I'm going to replace them anyway as I have no record of them being changed so don't know how old they are.Looks to be running a tad rich (they're quite dark). Other than that they look pretty fresh to me, I'd probably clean them up (brake cleaner works well) and re-gap them TBH. Unless you know for sure they're really old, say 25k plus miles or 5 years. Better safe than sorry in that case, you don't want to lose your tip down a bore (for once in your life at least) due to brittleness.

Cheers Krzys. That's useful to know and maybe the answer.I'm told by Tegiwa when they mapped the track car the other week, that OEM set up on the EP3 is a fairly rich map, so maybe it's that and the plugs are of age/mileage ready for changing?
Not recommended to gap iridium tipped spark plugs as you can damage the iridium tip.I'd probably clean them up (brake cleaner works well) and re-gap them TBH.

Gapping spark plugs is a thing of the past now. 9/10 times they’re already gapped to the correct manufactures specification when you buy the correct ones for your engine.
