Hi everyone I have changed the spark plugs for fabia 1.2 htp 2013 two times in one month, and they were a good brands but something in my car make them bad any advice ? 

Welcome.

 

Hopefully someone that knows your engine type and issues will be along.

 

What plugs are you fitting, Make & Code Number?

 

Why did you have to change newly fitted new spark plugs, did the tip burn out after fitting?

Were you getting Misfires, or Misfire Codes logged?

 

Were they bought from a trusted source, do you know for sure the correct plugs and fitted with the correct gap?

Do you know the Ignition Coils are good?
