Industrial Injection 0986435621SE-R3 R3 Race Series Remanufactured 180HP 6.7L Cummins Performance Fuel Injector

The Industrial Injection 0986435621SE-R3 is a Race 3 (R3) remanufactured high-performance common rail fuel injector designed for the 2013–2018 6.7L Cummins diesel engine. Rated at 180HP over stock with a 78% increase in fuel flow, this injector is purpose-built for diesel enthusiasts seeking serious power gains beyond what a stock or mildly modified injector can deliver.

Built and calibrated in Industrial Injection's Bosch Authorized remanufacturing facility, each injector undergoes extrude hone nozzle processing and precision balancing to ensure consistent, matched flow performance. The result is a direct-replacement injector that delivers a smooth, clean idle alongside dramatically increased fueling capacity.

Key Features:

• Race 3 (R3) performance level — 180HP / 78% over stock fuel flow
• Built, calibrated, and tested in a Bosch Authorized facility
• Nozzle extrude honed for optimized flow and atomization
• Balances to a tighter tolerance than OEM for consistent performance
• Smooth, clean idle characteristics
• Direct drop-in replacement — no modifications required
• 1-Year Unlimited Mileage Warranty
• Includes new copper crush washer and o-rings for installation

Important Installation Notes:

• It is strongly recommended to replace injector connector tubes during installation to avoid warranty issues
• Only Bosch connector tubes (F00RJ01572, F00RJ01831) or Cummins connector tubes (3979419, 5346206) may be used — aftermarket connector tubes will void the warranty
• R3-level injectors require a performance CP3 fuel pump upgrade for proper operation

Core Charge Notice: A core charge of $150.00 applies to this injector. The core charge is fully refundable upon return of your original injector cores within 90 days, provided they pass Industrial Injection's inspection criteria.
