Hi Guys

I recently changed my plugs to the NGK Spark 766 or Copper Core Part No. IMR9C-9HES plugs and have developed a misfire . its seems to happen across all cylinders. my thoughts are that the plugs are too hot . has anyone had a similar experience or can recommend a decent set of plugs



Cheers

The 1.4 TSI GTI engine is quite sensitive for spark plugs. Maybe look for an alternative (i'm sorry, I don't know which ones to advise)
