tested some glow plugs for the old 5.7 diesel. the only one that I could get for today was an autolite so I torture tested it. with 12.5v at the plug on for 5 minutes it never failed. I did this test 10 times. they take right at 30 secs to be fully warmed up and draw 7.2 amps. The only other brand plug that I can get is bosch and will test them the same way, but I plan on putting them in my truck.
