Ever since I got my BX it has been a pig starting from cold especially on the colder mornings, being winter here thats nearly everyday. Well since I got the spare parts car I started to think how unfair a car that was about to be dismantled started first time and mine just would be pig headed

Decided to change the spark plugs and after a checking with our local mechanic we came to the conclussion that the information in the parts books he had was incorrect. After consulting the haynes manual and BX handbook we finally figured out the ones he could get were Champions.
Sweet so out comes the old ones! Question to me is they looked fairly new probably when the last owner who was a Citroen Mechanic replaced them.
Here is what I took out Eyquem RFC58LZK.
Now they are not in any of the parts books I have so what car do they fit?
Ever way the BX started first time from cold with a little blip of the accelerator. Seems I cured one problem!
But wondering why the heck he put in a French made spark plug of the wrong type?
