How much energy is put into a glow plug on average?

How can I get that right balance where they work like they need to but I don't blow it out with too much power?

It varies with the type, but anywhere between 5A to 15A for 12v systems, so 4 plugs can be 60A which is why the cable used is a heavy gauge . The power is then between 60W to 720W.

  • Is there away i can cut start time by adding more power so ut heats up instantly? – user159665 Sep 13 '17 at 6:44
  • They may make ones that have a quicker response time... You could also change the supply voltage but I don't suggest that as some functions of the ecu may well be affected... – Solar Mike Sep 13 '17 at 8:03
