hi all. Does anyone know if you have to close the gap up on spark plugs when you turbo a j4 16v engine and you up the boost too about 1bar etc !. Many thanks chris

Ive got some ngk plugs in it at the mo. The reason i ask about gaps is i had a rs turbo once and when the boost was wound up it blew the spark out so just wondered if this was a problem on these engines too?. Cheers
