I've seen 2-plug heads but not 3. Fire it up on one then hit the other 2 once it's running iwth the ignitor. A metered ignitor will let you know the plug is hot.

It may allow the use of higher nitro. The rule of thumb is that the smaller the engine, the higher nitro you can run. Believe it or not, nitro is considered a slow burning fuel, kind of funny when you consider that we have the little engines cranking out 38-42,000 RPM. In the "big-block" .90's the 2- or 3-plug heads help to give you a better fuel burn so you can run more nitro than you normally would. We're seeing this also in everything from Top Fuel and Funny Car engines to the little 2.3 Liter in my Ford pick-up using 2 plugs per cylinder.

I did some research and did come up with Hallam Marine Hobby in Ontario, Canada but their site is down right now. I'll see if I can dig up someone else in the meantime.
