They feature a proprietary design with specialized nozzle honing for precise and consistent holes. Nozzles are flow-matched to a 1% variance per set, and injectors are flow-matched to a 3% variance per set. They are assembled using either new or Bosch remanufactured bodies. Core returns are required, with a $150 charge if no core is returned.
