Q: Does the CT-457 fine wire gap setting tool work for the Tempest UREM38S spark plugs?

Yes, this would work with the tempest spark plugs UREM38S.

Q: How wide will this gap fine wire plugs? I need a gap of .036 for my electro air ignition system. the plugs are currently set at .015.

This is a gap adjusting tool, but you will need a gap gauge to set the gap. I could not find a .036" gap gauge in our inventory, but a filler gauge may work for this.

Q: Q: How wide will this gap fine wire plugs? I need a gap of .036 for my electro air ignition system. the plugs are currently set at .015. You can not use normal Tempest spark plugs with an Electroair EIS. YOU NEED TO USE Electroair plugs which are made by Tempest. The ones I use are EARHM38SE… Please do not try to use regular Tempest thin wire plugs. Check with Electroair for your model engine..

We stock feeler gauges that are listed as .035/.88mm, see part # 15-05142. We also stock gapping tools, see part # 12-03391.
