I read over the sheet that comes with the heads and it says to use, among others, FR3LS A/C plugs. Are any of you using these? If not, what kind of plugs are you guys running?

Thanks in advance,

Im running the new urideum (sp) plugs from Bosch. I dont have the part # though. The parts store cross referenced them for me. They seem to work great!

I'm using those plugs in my TFS 23 heads. I gapped at around 60 and they work pretty darn good.
