99GT Posted May 7, 2018 Report Share Posted May 7, 2018 Just swapped these out of my daily driver, 2005 fiesta. Bought with no history and ive used it for a year now too. Thought it's due a service! Wonder when these were put in? Anyone pulled out worse? Lol 1 Link to comment Share on other sites More sharing options...

_Chris_ Posted May 13, 2018 Report Share Posted May 13, 2018 (edited) Were those in a marine engine from a shipwreck ? I suspect they were fitted in 2005 in the Ford factory. Edited May 13, 2018 by _Chris_ 1 Link to comment Share on other sites More sharing options...
slybunda Posted May 13, 2018 Report Share Posted May 13, 2018 Heh. 1995 fiesta mk3. Those plugs had done 9 years and 35k miles of use. Genuine ford platinum plugs rated to 40k miles. Plugs worked fine no missfire or issues at all. Thought id change them before they seized into the head. Made a lot of creaking noises when unscrewing out. Replaced them with denso iridium plugs. Noticed mpg increase straight away and car feels more torquey. Had the car 20 years now so next plug change will be around 2025 Link to comment Share on other sites More sharing options...
