A mate has just taken a graphite 1.9 part-ex for his miami 1.6, but it has a a damaged spark plug thread. he's thinking of tapping it out to clean it up. What size tap does he need?

You can get a thread chaser from machine mart for a couple of quid, I've bought one to use on my turbo lump, haven't used it yet though!
