Put a set of these in my 2LTE last week during the cold weather, and I must say they are incredible glow plugs. Build quality is great and they heat up very fast while concentrating the heat to the tip where it is needed. I ran one with jumper cables before installing and compared to some other plugs I had. The Duraterms kicked butt. Just throwing it up here incase anyone else is on the hunt for new glow plugs. Highly recommended and worth a few extra bucks. I ordered from the UK via Ebay, but there may be other sources.
