Specifications

The superior performance of the ISL comes from a constant flow of high-pressure fuel, injected with precise timing for optimum burn efficiency. Regardless of engine speed, the pressure inside the High Pressure Common Rail system does not fluctuate. An increased number of injection events per cycle results in an ISL that runs both stronger and quieter than ever before.
