Fiesta plug gap

Plugs should be set at the recommended gap from the factory. Just get the correct plugs and stick them in. Regarding brand, people will tell you different things, personally I reckon any of the recognised brands are much the same.

NGK plugs are pre-set

Hardly a helpful reply. Sometimes the recommended gap changes and the gap set when the car left the factory is not the correct one.

To the OP, plug gap should be 1.0mm. As for the brand of plug.... Motorcraft or NGK are best for these engines IME. I would avoid Bosch and Champion.

Haven't bothered setting, or even looking at a plug gap for years. NGK are always my first chooice plug. I have used Bosch with the four tips (can't remember the exact name) and had absolutely no complaints. The car was scrapped witht them still in the engine. I agree about Champion plugs. Absolutely s**te they are.

The plug gap for Zetec engined Fords was originally 1.3mm. This was found to increase the possibility of ignition coil failure, so the recommendation was revised to 1.0mm. It's worth checking the gap on this basis.

With over 25 years experience of owning Ford cars, I would only ever use Motorcraft in them. Agree 100% with NGK for everything else however.
