I thought I would start running review on glow plugs. For the most part there are many manufactures in which you can run on many different engines.

Please post up your reviews on your go to plug. I am curious on how the ofna plugs work.

I have only used a handful of different ones.

Arizona Weather:

Odonnell 97 T: Was ok seems to do well however longevity is not so great but they are priced well.

O.S P3: Has worked very well and they seem to last quite awhile. Somewhat pricey

Mugen JX P3: Has been the best plug I have used and they last a long time. They do cost plenty more than most plugs

Post up the reviews. It would also help if you state where you live as well. I am looking to find the most reliable plug with performance.
