Thank you for purchasing the AVPlug, The following are the instructions on how you assemble an AVPlug.  Firstly we have to prepare the core plug, to do this  we need to remove the threaded top part of the core plug, there are a variety of ways this can be done. 

The photo shows a hacksaw being used to remove the top thread of the core plug.

Dremel cutting of top thread of core plug.

Angle grinder cutting off top thread of core plug.  These are three ways one can remove the top threaded part of the core plug.  Do this step to all the core plugs you require for you installation.

  Example of of what the core plug should look like.  

Now we have to screw the core plug into the AVPlug base.  The photo on the right show this stage completed.  Place copper anti-seize paste on the threaded section of your core plug and screw it into the AVPlug base,  torque to 9 foot pounds.

Now that we have prepared all the AVPlugs required for your installation.  Now it is time to install the AVPlug on the your engine, this is done the same way as any spark plug installation on an engine is done.   

Place the copper washer on the base threaded part of the AVPlug, then place copper anti-seize paste on the threaded section of the base threaded part and now screw into top of cylinder (Jug) of the engine.
