Industrial Injection 0 986 435 502-R3 Race 3 40% Over LB7 Duramax 6.6L Remanufactured Fuel Injector

The Industrial Injection 0 986 435 502-R3 is a Race 3 performance remanufactured fuel injector for the 2001–2004 GM 6.6L Duramax LB7 diesel engine. Starting life as a genuine OEM Bosch remanufactured injector, each unit is extrude-honed and balanced to flow 40% over stock at approximately 28 LPM — delivering the extra fuel needed to support high-horsepower competition builds.

Key Features:

• 40% Over Stock Flow: Race 3 calibration for significantly increased fuel delivery over the factory injector
• OEM Bosch Foundation: Built on a genuine remanufactured Bosch injector, extrude-honed and flow-matched at the Industrial Injection facility
• Extrude-Honed & Balanced: Each injector is precision-honed and matched to ensure consistent, uniform fuel delivery
• Includes Installation Hardware: Comes with a new copper crush washer and O-rings for installation
• Direct OEM Replacement: Drop-in fitment for the LB7 Duramax platform
• Sold Individually: Allows targeted replacement or a full set upgrade depending on your build
• 1 Year / Unlimited Mile Warranty: Covered under the Industrial Injection OEM product warranty

For best results and to protect your investment, Industrial Injection strongly recommends replacing the injector fuel lines when installing new injectors — fuel line contamination is the most common cause of replacement injector failure. Pairing these injectors with an upgraded turbo and CP3 high-pressure fuel pump (such as the 85% over Dragon Fire Pump or a Dual CP3 Kit) is also recommended to maximize efficiency and keep EGTs in check.
