I would put in Denso Iridium plugs. These have a fine single electrode which is very hard wearing. The four electrode plugs can mask the spark. It is a common myth that multi electrode plugs give more sparks. They dont. They spark to the nearest electrode and then when another become closer due to erosion it then goes to the next one. ( this makes them last much longer without using special metals ). I use Iriduim plugs in both my car and bike. My details are below if you wish to order some.

I had some new ish +4 plugs in my 944... replaced them with cheapo £1.50 a pop Bosch jobbies and it ran far better. at £5 for 4 I wasn't worried if they didn't last as long!
