Just an update. I didn't get round to doing the plugs get. I did not realize how much crap is in the way on stock RB. It.is definitely getting worse. I'll get on it soon
New plugs. They were NGK iridium plugs. I cant quite remember the number. Looked like the import type of plugs not the UK. Also looks like it has aftermarket coilpack.
Sorry, I meant do you know what the plug gap was on the plugs you pulled out? What colour are the coilpacks?
