Delphi EX631066 Remanufactured Diesel Fuel Injector

The Delphi EX631066 is a remanufactured diesel fuel injector engineered to original equipment (OE) standards. Built by one of the world's leading OE diesel fuel injection suppliers, this injector delivers the same exacting performance as the factory original part it replaces.

Each Delphi remanufactured injector is completely disassembled, cleaned, and inspected for wear and damage before rebuilding. All critical and worn components are replaced with new parts, including a new nozzle, NOP spring, and solenoid control valve (NCV), ensuring OE-level quality, performance, and durability upon reinstallation.

Key Features:

• Remanufactured to OE specifications using original factory components and test procedures
• Surface lapping of critical components ensures pressure sealing of sub-assemblies
• 100% new O-ring replacement for proper sealing and leak prevention
• No internal seal rings minimizes fuel leakage during operation
• Recessed fuel exit design minimizes plugging and improves spray consistency
• Accurate, controlled fuel spray pattern reduces emissions and improves cold-start performance
• Tested on specialized equipment for correct fuel delivery, timing, and pressure
• Produced in a Delphi ISO 9001:2008 certified remanufacturing facility
• Backed by Delphi's decades of OE diesel powertrain expertise

The Delphi EX631066 is a direct-fit, standard replacement diesel fuel injector. A refundable core deposit is required at the time of purchase — return your old injector core to receive the core charge refund.
