Can anyone tell me which are the best/correct spark plugs for my fiesta, looked on euparts but there's a few different listed for my reg when i've looked on europarts. Theres 3 different Bosch ranging from  3.50 to 15.50 theres also an NGK and a denso.

1.25 mk6 fiesta zetec (climate - don’t think that makes any difference)

thanks 

I've always used NGK without any problems. 

For a 2006 Fiesta 1.25 it should be part number TR5A-10. The 10 means that the gap is preset.

Deffo NGK on a 1.25 Zetec engine, as David says..... gapped at 1.0mm.

 

Hello , I don’t know if anybody will be able to help me but I have a slight problem with my fiesta , it is a 2006 semi-auto 1.4model that I bought last April . While I am driving along there is a noise from the rear that sounds like some abrasion of something , is there anybody that I could take the car to who would be able to help me find out what the noise is and if it’s a hindrance , then if possible I would like to fix it . I live in Wallington Surrey .
