Hi Guys,
I am using an E-magnet with NGK spark plugs on one side of my O-320-D2J engine and have installed adapters in each cylinder to reduce the thread size from 18mm to 14mm.
During recent inspection I found one of these adapters cracked (in fact completely broken). I ordered and received new adapters from Aircraft Spruce but I don't know with which torque value to install them in my cylinders. Your advice is more than welcome.
Here's a picture of new and old:
