GBR 832-11203 Fuel Injector

Reman Multi Port Fuel Injector Overview

GBR 832-11203 is a remanufactured multi port fuel injector built for direct replacement in a wide range of GM and related applications. It is remanufactured in the USA using a 15-step process and tested under multiple operating conditions for flow rate, spray pattern, coil resistance, form, fit, and function.

This injector is a fitment-based replacement for vehicles such as the Chevrolet Silverado 1500, GMC Sierra 1500, and Cadillac Escalade. Part number 832-11203 is also referenced for several OE and aftermarket cross applications.

Key Features

• Remanufactured OEM-style fuel injector for multi port fuel injection systems
• Tested to meet or exceed OE specifications for flow rate and spray pattern
• Verified for coil resistance, form, fit, and function
• Includes new external seals and o-rings
• Remanufactured in a U.S.A. facility using a controlled 15-step process
• Cross-references select OE and aftermarket numbers for the same application

Detailed Description

GBR Reman Multi Port Fuel Injector 832-11203 is intended for direct replacement service on supported GM trucks, SUVs, and utility vehicles. It is compatible with applications including 2007-2009 Chevrolet Silverado 1500, 2007-2009 GMC Sierra 1500, 2007-2009 Cadillac Escalade, and related models listed in the fitment data. The remanufacturing process focuses on restoring injector performance to OE-level specifications so fuel delivery remains consistent across the supported vehicle range.

This part cross-references 12580681 and 19421333 for the same application.

What It Helps Fix

• Rough idle caused by inconsistent fuel delivery
• Hard starting related to poor injector spray pattern
• Misfire conditions tied to restricted or worn injectors
• Fuel trim imbalance from uneven injector flow
• Loss of engine performance from degraded injector operation

Installation Notes

• Verify vehicle year, make, model, and injector application before installation.
• Use the fitment list to confirm the exact supported configuration for your vehicle.
• Inspect fuel rail, connectors, and sealing surfaces during replacement.
• Replace worn seals and o-rings as part of the service procedure; new external seals and o-rings are included.
• Follow factory service information for fuel system depressurization and injector installation.

Quality Assurance

Each injector is tested under multiple operating conditions to confirm flow rate, spray pattern, coil resistance, form, fit, and function against OE specifications. The remanufacturing process is performed in a U.S.A. facility using a 15-step procedure for consistent output and repeatable performance.
