1990timeismoney Posted July 23, 2013 Posted July 23, 2013 Hi all does anyone now the standard gap size for ngk spark plugs.ThanksLuke Quote
AdamB Posted July 23, 2013 Posted July 23, 2013 1.1mm. The largest gap possible, but it depends on your engine spec and what kinda condition the rest of your ignition system is in. Quote
1990timeismoney Posted July 23, 2013 Author Posted July 23, 2013 Thanks for the reply engine is standard running td04 at 1 bar with all supporting mods will 1.1mm be ok for this setup Quote
AdamB Posted July 24, 2013 Posted July 24, 2013 You'll prob want heat range 7's. It's a bit trial and error, always start with the largest gap then if it missfires then make the gap smaller. Quote
AdamB Posted July 24, 2013 Posted July 24, 2013 (edited) 1.1mm is the stock gap for an OEM un-modified engine. Edited July 24, 2013 by AdamB Quote
