Plugs/coils never changed at 47000km.
Will be ordering a brand spanking set soon.
Any tips/advice?
Anyone recommend local shop for plugs and coils? (usually order from USA)
Been reading the site for a while and impressed with the database of info already posted.

Def sounds like you know the issue
I'd change all plugs, coils as needed.
