Industrial Injection 0986435621-R3 Race 3 Remanufactured 6.7L Cummins Common Rail Injector 180HP 78% Over

The Industrial Injection 0986435621-R3 is an OE Spec Plus remanufactured Race 3 (R3) common rail fuel injector engineered for the 2013–2018 6.7L Cummins diesel engine. Flowing 78% over stock and rated at 180HP over the factory injector, this R3-series injector is designed for serious performance builds where significantly more fuel delivery is required.

Each injector begins as a genuine OEM Bosch unit that is expertly remanufactured and calibrated using Bosch machines and procedures to ensure industry-leading reliability. Every unit is individually tested on a state-of-the-art test stand — including resistance testing, system leak testing, purge cycles, idle speed, mid-load, full load, and static back-leak tests — to verify it meets or exceeds OEM specifications before leaving the facility.

Key Features:

• Race 3 (R3) Performance Series — 78% over stock fuel flow for substantial power gains
• 180HP over factory injector output rating
• Remanufactured using genuine OEM Bosch components and Bosch-certified equipment
• Direct drop-in replacement for the factory 6.7L Cummins common rail injector
• Extrude honed and precision balanced to tight tolerances for consistent fuel delivery
• 1-Year Unlimited Mileage Warranty included
• Includes copper crush washer and O-rings for installation
• Bosch OEM part number cross-reference: 0986435621

Installation Note: It is strongly recommended to replace connector tubes whenever installing new injectors. Only Bosch (F00RJ01572, F00RJ01831) or Cummins (3979419, 5346206) connector tubes should be used — the use of aftermarket connector tubes will void the warranty. Contamination from connector tubes is the most common cause of new injector installation failure.

Core Charge Notice: A core charge of $150.00 applies to this injector. The core charge is fully refundable upon return of your serviceable core.
