The R7376 plug has an identical nose configuration to the stupid expensive shorty plug and cap for less than 1/4 the price.
Its only difference is the insulator length , thus it uses a " normal " resistor plug cap.

Red or blue...Specifications of material are the same on ngk page

Red or blue...Specifications of material are the same on ngk page

But try putting the red one on a shorter plug.
Works either way with the shorter one.

So, i finally made a calculated pipe for my violated SGM Kartengine.(bored out to 144cc)
Running on E85 i made the other day 48.2hp to the wheel at 12700rpm
Depending on what is correct when calculating losses it is between 51,9 or 56,7hp to the crank(my dyno reports ~10% but some says it should be 15%.

However, I ran an BR10ECS.
The diskussion above about that expensive NGK plug, is it known to make any more power than 'normal plugs'?

My plug and dynosheet, and below link to a livefeed when i was dynoing it.
Dynosheet shows before and after testing with a no calculated pipe and a calculated in Mota.
