Spark Plug Tech

Post by plynn41 »

Can anyone explain the different types of NGK plugs and what is the logic behind the different designs? (I.e. "eg" vs. "es" vs whatever else there is).

Also, what are some of you guys running for plugs on modified engines on gasoline?

Thanks!

non resistor plugs DONT WORK if your running a 99 250 ignition
im running a BR8EG right now, the G is a smaller electrode, but not some fancy metal
the 450 will have less power and will be harder to start, and will be heavier, but to make up for it it will require more maintenance.
