There's a group buy on at the moment for PFR7b. You may get in if you're quick!
Set to 0.65mm
Changing the plugs is not hard but is more involved than the average engine! You need to remove the air cleaner (2 bolts) and the washer bottle on the other side (suck the contents out first) Unbolt the coil packs and remove. The plugs are deep in the cam covers so you will need an extension on the plug socket (may need to experiment with the length)
Sounds a bit of a job, but thinking about it is worse than actually doing it!
