does any one know the best spark plug ..gap ..and heat range for a ef 4ltr turbo car is only running low boost at the moment was told from spare parts mob that the standard ef spark plug would be fine for a low turbo boost application only need to gap them down to suit so as not to get spark blow out is this info true and correct ...thanks

I'd probably use NGK ZGR6B11's as specified for XR6 Falcons, and Falcons on LPG, as for gap, maybe gap them down a little bit, but I'd almost be inclined to say the standard gap should be fine even for turbo. Basically, turbo shouldnt make any difference to the spark plugs u should run.

heat range to high= detonation/pinging.
plug gap not reduced = spark blow out at certain boost levels..
