Adamp Posted December 7, 2018 Report Share Posted December 7, 2018 Does anyone know what the gap measurements should be? Replacing the plugs and not familiar with this engine. ( I tried the search but not joy) Cheers. Quote Link to comment Share on other sites More sharing options...
mk2 Posted December 7, 2018 Report Share Posted December 7, 2018 Plug gaps are not as critical as people think... usually about 0.8mm does the trick. 0.6-2.0 will work. Plug temperature will affect performance though. I like to run a plug with a heat rating one hotter than standard. Means you can run a bit richer for fractionally more power when you remap- and no plug fouling. Nice clean plugs even when rich, because the extra heat prevents the soot from sticking. Changing plug leads and ends don't have any effect unless the original ones are faulty. Quote Link to comment Share on other sites More sharing options...
Sausage Posted December 8, 2018 Report Share Posted December 8, 2018 Reasonably sure they come in the box with 1.0mm gap, but I'd be aiming at 0.8mm. gap increases with wear. A slightly hotter plug is a good idea too. Quote Link to comment Share on other sites More sharing options...
