hello guys,
i have 1998 audi a3 1.8T (AGU).i've done big turbo upgrade with 2871.the car made around 400 hp but i got some problems with spark plugs.i use NGK PFR6Q spark plugs.but sometimes i feel some miss fire and i when put the spark plugs out ,they 're like black as coal.then i tried BKR7Es and the result was same as PFR6Qs and i've checked my A/F and its around 10.5-11.
so what do you use for your BT upgrade ? or any suggestions ?
