Review on 🔧 Time-Sert® M14x1.25 Spark Plug Thread Repair Kit - Premium Quality Solution (p/n 4412E-111) by Josh Clifton

WARNING! This product works but use caution and be aware. I used it on a 2007 Honda Accord and the installation went smoothly. Make sure the cylinder is lowered from the spark plug. I used bearing grease and removed it several times to catch the sawdust. I repeated the measurements to be extra careful and I also had a camera with me. I used the vacuum and started the car with the spark plug removed to clean up any sawdust that might have been missed. The cylinder held a vacuum and the spark plug worked in the new thread. BUT . As far as I can tell, some fine shavings from the exhaust got into the ERG (nothing difficult to clean or replace) and clogged the ERG diaphragm on the intake (er, rotating misfires). This is a big deal to fix. So be careful when doing it with your heads on. You can remove the ERG valve at launch.
