AdamB Posted July 23, 2013 Share 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 Link to post Share on other sites
1990timeismoney Posted July 23, 2013 Author Share 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 Link to post Share on other sites
AdamB Posted July 24, 2013 Share 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 Link to post Share on other sites
klyfax Posted July 24, 2013 Share Posted July 24, 2013 0.6mm - 0.8mm. 1.1mm is for Non distributors. Quote Link to post Share on other sites
AdamB Posted July 24, 2013 Share Posted July 24, 2013 (edited) 1.1mm is the stock gap for an OEM un-modified engine. Edited July 24, 2013 by AdamB Quote Link to post Share on other sites
