How to find part number for my Fiesta spark plugs?

I need to buy some spark plugs and want genuine motorcraft plugs. However there are a million types and not sure which exact one I need.

Any ideas on how to find the exact one? THanks

Factory plugs used in the later 1.25 fiestas were made by Bosch for example.

What year is yours any why do you want motorcraft ones?

I have a 2004 Fiesta, 1.25l petrol. Were these also bosch?

It was recommended that I use Ford spark plugs only by the AA guy.

Just looking at spark plugs in general, some have 4 little leg things (no idea what they're called - electrodes?) and others have just one. Does it make a difference which one I use?

Just go into your local motor factors and give them your reg no. They'll be able to give you the correct plugs.

Ford don't have a plant where they manufacture spark plugs, they'll have spec'ed them and given a contract to another company. I had a '99 Fiesta, 1.25, always just put in whatever the motor factors gave me

If it were me I would go to the motor factors and use whatever spark plugs they give me, but anyway here are the part numbers you need for the 1.25 litre engine (2002 - 2008). It's the same part number for all petrol engines except the 1.3 litre in fact.

Bosch HR MEV Gap 1.3mm
Motorcraft AYFS 22 C Gap 1.3mm

Any good motorfactors will have genuine Ford plugs in stock. Fords are quite fussy about the correct plugs, as are quite a few brands actually
