Review on Bosch Automotive 80028/0250202022 Duraterm Glow Plug: Superior Performance and Durability for Efficient Ignition by Robert Demissie

Excellent glow plugs. The check engine light on my VW Jetta TDI 03 came on the other night, the code was for the cylinder #2 glow plug. I tested all 4 plugs for resistance to make sure it was the plug and not a wiring issue, which appears to be the case happen occasionally. My check revealed that the spark plug in cylinder #2 had died. It was a Beru brand that I put on maybe 5 years ago or about 20,000 miles. I don't know much about glow plugs, but it seems to me that their lifespan is a bit short. That's why I chose Bosch and Amazon was able to send them to me quickly thanks to Prime! I've changed all 4 spark plugs (cleared the code and no problems since) and will be sourcing more replacements just in case the local parts shops are out of stock and the nearest VW dealer is an hour away from me!
