Review on 🔧 Enhanced Powerbuilt 14MM Spark Plug Thread Repair Kit: Model 648421 by Jose Guevara

(product) bought these to fix a problem with spark plugs coming out of the engine while it was running on 3 separate occasions. I have tried others and was concerned that the terminal on the spark plug was the same size and wanted to try these as they had a collar. I knew when they hit bottom and didn't go too far into the cylinder head after about 2-3 months I started getting misfire codes and a few days later I lost one of my plugs again that had this connector (looks like as if it had started to untie) and after checking one of the other two that still had it, I noticed that the threads were also untied (seller) Fast and quick transaction
