Powerbuilt 14mm Back Tap Thread Repair Tool - 640811
Mar 31, 2020
Best cheap tool I've bought in a while.
Recently bought a 88 porsche 911 and when changing the plugs I found cylinder 6 was seated all of the way. Put new plug and it got tight within four rotations. The plan was to overhaul but not this early. Found this tool and it worked perfectly. It does require patience and good finger muscles,but I will take 2hrs of this verses pulling the head. New spark plug went right in and was able to torque it to spec. Saved me a lot of time. THANK YOU!!!!
