I recall that NGK BP9HS are the recommended type from memory, but I fitted Accuspark Iridium plugs into my B20 144 last year and found starting and running so much better. Here's a link:

The iridium are resistant to fouling and will generate a spark at a lower voltage than a conventional fat electrode plug so starting may be improved when the voltages drop during cranking. The iridium electrode is also more durable than the conventional electrode which is why they are used in cars with extended maintenance intervals. Purchase from a reputable vendor because there are NGK iridium EBay fakes on the market. They look correct; but, the center electrode is not iridium so they burn up rather quickly.

You are of course correct, I was thinking 6 but somehow typed 9, glad you agree that iridium plugs are a benefit, thanks.
