For those who run the 10.5 or 11 heat range plugs, how do you all remove and or tighten the plugs? The engine block has a lip and I can't get a traditional 13/16 spark plug socket to engage the plug to torque it. All the "thin wall" tools I've google searches so far don't look think enough. Any other tips or tools to remove or torque these plugs? See picture.

 

They'll work. I simply bought a cheap spark plug socket at Autozone and ground down the end with a bench grinder until it fit.

If you do buy one you have to get one designed for a rotary, like from Racing Beat or the like.
