So the idea with these is to place the electrode in the optimum place for igniting the most fuel ? I haven't heard of these before now. Interesting I will do some research and look into this. Thanks
Indexing spark plugs in 22 might get you some improvement in the combustion chamber. Some combustion chambers and head designs may actually create better flame propagation and turbulent velocity with the gap facing in a different degree angle from the exhaust valve - which is often cited as the proper valve to point the spark plug gap.
Some head designs might show improved combustion and flow by indexing the plug gap to the intake valve.
Without testing, you probably won't really know. A stock 22 on an engine dyno, it may be difficult even record a 1% or 1 HP improvement in the torque numbers.
