- 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.
