RE: A good guide for selecting the correct Glow Plug...
I had seen the plug chart before and was delighted to see it.
Being familiar with the longer OS pulgs I was puzzled to see how the guy had some categorized
But the chart is still useful for other brands of plugs if you compare them with the genuine OS wheel
Glow plug heat ranges are a mysterious thing to must of us. We usually learn our little realm but the other brands we do not know about.
On brand's "HOT" plug may not be as hot as another brand's "HOT" plug
What is a hot plug?
What makes a coild plug?
