O.S./Protek Glow Plugs
 

Hello, I need to order some more P3 glow plugs and I have a quick question. I see the "gold" plugs and the "silver" plugs. Is there really any difference? I cant find any data on it but the gold ones seem to be a bit more in cost.

Thanks!

Not much difference. I’ve run both and they seem identical performance wise.

same goddam thing!! its a marketing raquet!

Awesome, thanks for the info!
