The Story
Delphi GN11125 Ignition Coil Overview
The Delphi GN11125 ignition coil is a standard replacement coil-on-plug unit built for electronic ignition systems. It is engineered to OE design specifications and endurance tested with quality materials to support fast starts, steady engine performance, and efficient fuel use.
Compatible With 2019-2022 Chevrolet Silverado 1500, 2022 Chevrolet Silverado 1500 LTD, 2019-2022 GMC Sierra 1500, 2022 GMC Sierra 1500 Limited, and 2020-2022 Cadillac CT4 applications.
Key Features
- Coil-on-plug ignition coil for electronic ignition systems
- 12-volt design with a single female elliptical connector
- 4-blade connector interface with 4 male terminals
- Standard replacement grade for OE-style service
- Black housing with 2 mounting holes
- Mounting hardware included
- No external resistor required
- No coil wire included and not oil filled
Detailed Product Description
Delphi GN11125 is built for direct ignition service on late-model GM trucks and Cadillac applications. Its coil-on-plug design places the ignition coil directly at the spark plug, helping maintain consistent spark delivery under normal driving and load conditions. Delphi manufactures ignition coils to OE design specifications and tests each unit for durability, making this part a practical choice for Silverado 1500, Sierra 1500, and CT4 repairs where ignition performance has declined.
This part cross-references Standard Ignition UF912 for the same application. The GN11125 part number is also commonly searched as Delphi GN11125 when sourcing an OE-style ignition coil replacement.
What It Helps Fix
- Hard starting or extended crank time
- Rough idle and engine misfire conditions
- Loss of spark strength under load
- Reduced fuel economy caused by weak ignition output
- Check engine light concerns related to ignition coil failure
Installation Notes and Tips
Verify connector shape, terminal count, and mounting style before installation. This coil uses a 4-blade female connector, 2 mounting holes, and a blade terminal design, so matching the original part configuration is important for proper fitment. Inspect the spark plug and related ignition components during service, and replace any worn parts that could affect coil performance.
Quality Assurance
Delphi designs and endurance tests each ignition coil using quality materials and OE-based engineering. The GN11125 is built as a standard replacement ignition coil for consistent service on supported Chevrolet, GMC, and Cadillac vehicles.
