.028 according to these but they’re “unofficial.” I don’t see it in my WSM… my plugs came from Ricambi at .020 https://www.carid.com/2009-ferrari-599-ignition-systems/champion-racing-spark-plug-3445894086.html https://www.stockwiseauto.com/auto-parts/ignition/secondary-ignition/spark-plug?Year=2007&Make=Ferrari&Model=599%20GTB Sent from my iPhone using FerrariChat
Another member sent me the owners manual instead of WSM so no wonder why I’m not finding this info lol. Ty for the help Sent from my iPhone using FerrariChat
Pretty big range, .023-.028”. Any preference or pros/cons between? Sent from my iPhone using FerrariChat
Iridium won’t wear as fast as copper so I’ll go bigger gap. I’ll go with .028. Too small of a gap creates weaker spark. LP will have no trouble created consistent spark Sent from my iPhone using FerrariChat
keep them consistent in all 12 .. if you do high rpms or run rich ... i would go lower vs higher .. Maybe else with that specific experience can chime in
