00 1.8 Spark plugs - Focus_Driver

I recently bought an x reg 1.8 focus and want to change the spark plugs. I saw some with 4 cores (?) in Halfords and they were only £20 for 4. Only thing stopping me buying them is that the current ford motorcraft ones fitted seem OK. They're not worn, and they're like a brown/tan colour. The spark plug gap is about 2mm but the manual says its should be 1mm.
Should I fit new plugs with the 4 cores and would that give me better mpg, perfromance etc over standard ones? The car starts and runs fine at the moment. And should I adjust the plug gap to 1mm?

Reason why i want to change them is I will be be doing a full service on the car so may as well have everything done.

I hope the car is a 1.8 petrol and not a diesel as the title suggests.If is is a petrol ,then stick with the standard motorcraft plugs or those made by bosch or Ngk.A gap of 2mm is excessive .new plugs reqd.Don't bother with the 4 electrode type.hth

I agree, just use the standard Motorcraft or NGK plugs. Also, if you buy the correct plugs, the gaps will already be correct and all you have to do is put them in. Plug gap for a Zetec engine as used in a Focus is 1.00mm.

It is for a petrol, my previous car used to be a tdci but now I have a 1.8 zetec. I don't know if the gap is caused by use over time but the plugs look in very good condition. I will change them since they're only £12 for a set, and not bother with the 4 electrode gimmicks .
