Reasonably well I'd say.. Wouldn't be worried about much.. Would have to see the other plugs to be able to diagnose anything, if you were fault finding.

i.e. that plug looks ok but along side the others it may be a problem plug..

all 6 are liek that. To me it looks as the though the combustion is pretty much spot on. Light brown colouring... no wet or large deposits etc.

after i'd taken them out, i decided they we worth keeping for spares.
Not cheap plugs, but no idea how long they'd been in etc.

Replaced the HKS (rip offs... just buy the DENSO ones... HKS just rebrand them) with NGK IX's.

Doesnt neccesarily mean its running rich.. Those plugs dont indicate rich running, could just be unburnt fuel when you lift off etc.. wouldn't see it as an issue.. Its better to overfuel than to be running lean anyway..
