P3 vs. T3 glow plug
What is the difference between a P3 and a T3 glow plug. They both look identical

The P3 is made by OS. The T3 isn't. Most of the T3 plugs look to be SH made. You'd have to run both to see how they perform.

Yeah it can get confusing since the ProTek Samurai engine was an OS and they did sell ProTek branded plugs to go along with it. And then they were selling the ProTek LS5 which was a Nova. What really gets me is they changed the temps for the plugs. An SH T4 is called a "medium" whole the ProTek T4 is called a "hot" plug. Seems to me that ProTek decided to change the making when they're the same plugs...
