You are watching: Spark plug gap on 4.3 vortec


I\"ve to be seeing some men talking bout setting the void of the plugs in a vortec down to 0.40 rather of 0.60, mine space at 0.60 and also it runs an excellent but if dropping it under to 0.40 will help it out i will execute it however I aint uncovered a directly answer top top it yes, really so lets obtain some feedback ~ above this cause Its grounding in my head. Thanks

Gapping them at .060 will give you a much better spark & fire the mixture better & v gas pull close $4.00 a gallon this is whereby I\"d leave them. Gapping them under to .040 only gains you if your coil is weak, or your wires are marginal because a .040 gap is simpler to jump. Also some lazy types set them at .040 since as the void erodes after countless fireings castle don\"t have to R&I the plugs & regap them. They just erode native a .040 space to the .060 or beyond & by the time the gaps are obtaining too wide, it\"s time to change them anyway so they never need to R&I the plugs except to replace them.

Mike Heartbeat simply sent me an e-mail with a attach that tells why girlfriend DON\"T change plug gaps top top iridium or platinum plugs. He said the iridiums room gapped at .040 & the platinums are gapped in ~ .060 & you need to not try and readjust them. Mike knows a lot
around this ingredient so I would certainly follow his advice. Since yours have actually the .060 gaps I\"m guessing you have the AC Delco platinums, so if you have actually the platinums gapped at .060 leave them there.
