Our company was formed to help customers increase power, improve fuel efficiency, and reduce engine emissions that contribute to global warming. To accomplish this, we focus specifically on improving the ignition of fuel inside the combustion chamber. The advanced DiamondFire design actually increases combustion pressure in the engine. Faster flame speed and improvements in the direction of the flame front result in a marked and proven increase in power output, fuel economy, and reduced emissions in gasoline engines. We have verified this using the most sophisticated testing equipment available today.

Black Onyx coating helps reduce corrosion. Copper core provides great heat transfer and helps maximize plug durability. Ribbed suppressor seal extends resistance and helps prevent spark 'flash over' and misfires. Nickel-chrome alloy sheathing helps prevent corrosion on center electrode.
