with the air/fuel mixture promoting a faster growing and larger
flame kernel, which puts more fuel to work providing more power
and fuel efficiency
Multiple sharp edges on the patented stamped ground electrode
provide long life and maximum performance
Rolled threads resist cutting of aluminum cylinder threads
Triple chrome-plated nickel shell
More power, better fuel efficiency, lower emissions
