Spark plug temperature

Hello, I dont know which temperature of spark plug to use in my Fiesta MK5 JH, JD 1.3 51kW. Motor number A9JA. I

 

I basically put my VIN into autodoc and others and they offer me spark plugs in wide range of temperature. Heck they dont even show that number, you gotta do "research" to find ignition temperature. I read that choosing this wrong can lead to either early ignition, before piston reach correct position, or clogging of the spark and increasing resistance between earth and electrode, thus not sparking correctly. 

 

Any help? Where to find what temperature my car needs or something please.

    I think you need Ford part 1787829 or try searching Ford item 2050957. As an alternative I am pretty sure the NGK equivalent is TR5B-13.
