I am personally using these plugs, and I find that they work very well. They are a single pin plug.2 - Good Spark Plugs
Ok, so you have you good petrol being sprayed into your cylinders, now you need to make sure there is a good spark. The OEM plugs are great but improvements can be made for a small cost.The best plugs out there are NGK IRIDIUM IX plugs. They are brilliant and the affects can be felt right away. The car is smother through the rev-range and pulls better at low revs. They are cheap too and should only set you back around 35GBP ($70).DONT go for Platinums as they are very problematic and can cause some very strange engine issues. Iridium has a massive melting point and so the electrode gap stays the same no matter how hot or how hard you push your carPirate (Pete)
I'm going to have to point you the sticky at the top of the forum about MODS... but here is a piece from it.

Hope this helps.
Nothing wrong with the OEM Bosch plugs, either...
I normally use Bosch but there's a guy who put a different brand plugs the one time and the take off was amazing, he wouldn't tell me which brand though, "his secret" he said and he's relocated now and i don't have his details so thanks again guys!
