gsac132 Posted January 7, 2012 Share Posted January 7, 2012 does anyone know the correct spark plug gap for a 99 ej25 s.h.o.c engine Link to comment Share on other sites More sharing options...
davebugs Posted January 7, 2012 Share Posted January 7, 2012 (edited) Most are .044 Check with the place you bought the plugs. If you purchased the correct NGK's they always come gapped correctly it seems. The gap is part of their part # I believe.

Fairtax4me Posted January 8, 2012 Share Posted January 8, 2012 .044" I don't think it would work too well with a .44" gap. Link to comment Share on other sites More sharing options...
mattocs Posted January 8, 2012 Share Posted January 8, 2012 As was already said, NGK plugs come pre-gapped (and are the best!) At least they have been every time I've done the plugs in my Subaru, Hyundai, and Suzuki motorcycle. And I LOL'd at the .44". :-P Link to comment Share on other sites More sharing options...
