Spark plug temperature

Hello, Im looking for new spark plug for my Fiesta MK5, FIESTA (1H1), motor type A9JA, 2004. But from what I was told, I gotta choose temperature right otherwise it can ignite fuel too early and potentialy damage engine or clog. But I do not know how to find such number, I tried to search many forums to find it. When I put my VIN into any seller. They show huge variety of spark plugs with different range of temperatures which they dont even list on their pages, you have to find them always elsewhere.

 

So is there any way to see or know what temperature does my car support? Anything will be helpfull to me.
