Hi guys! 
I have heard good things about these spark plugs for Audi TTS 8s mk3 (310hp) when you ride the power (around 400hp): NGK R7438-8
I kindly wanted to ask you if along with these performance spark plugs you have to change the ignition coils too or if you can keep the stock ones.
Thank you very much
