thanks for information fellas - i bought the car from pugo off here and he did tell me what plugs to use but i cant remember and havent had them out yet to look. Thought i would ask for a few more opinions and see what teh outcome was. My idle is a bit poo in the morning but other than that it runs good. I think they are 071's - when i heard they were cheap i kinda thought nah it cant be them its bound to be the super expensive plugs that i need - just dont wanna melt them on boost!
