Review on ACDelco 9G Professional Glow Plug by Robert Oner

After a budget glow plug route and repeated failures, I finally gave up and ordered an AC Delco. A month has passed and the fix remains. Definitely better pay extra and the problem will go away. Now my bitch during the day has nothing to do with the quality of the product, but people send the goods back and Revain does not check the product. This block was missing the top nut and showed signs of having been previously installed and this must have been discovered by Revain on return. Luckily the glow plug was fine and I have no idea why it was used and returned.
