• Includes: 8 Bosch reman injectors at 300% over, copper washers and O rings, and a calibration sheet for the set.
• Matched set: Nozzles are enlarged with micro EDM and abrasive flow honing and matched to flow within 1%. The set is tested at multiple calibration points and balanced to plus or minus 1%.
• Checked six times: Every nozzle goes through six separate quality checks before it goes back on the injector.
• Remanufactured by Bosch: All moving parts and wear surfaces are replaced. Very few parts are reused.
• Internal modification: Exergy modifies the injector internally to keep its target rate shape at this size. It raises fuel output across the whole range, including idle and pilot, so custom tuning matters even more.
• Required: Custom tuning is needed to take full advantage of these injectors.
