The Rentar Fuel Catalyst is made up of a patented combination of metals and rare earth elements. Unburned fuel is blown out the exhaust as emissions and wasted energy. The Rentar Fuel Catalyst triggers a reaction which improves combustion resulting in a better burn increasing the horsepower and reducing emissions.

Rentar Fuel Catalyst helps to reduce air pollution (C02, NOx, CO, SO2, Particulate Matter & Black Smoke), reduce fuel consumption to save money and also reduce maintenance costs by extending time between oil changes.
