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.\u003c\/p\u003e\u003cp\u003eThis 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.\u003c\/p\u003e\u003ch2\u003eWhat It Helps Fix\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003eHard starting or extended crank time\u003c\/li\u003e\n\u003cli\u003eRough idle and engine misfire conditions\u003c\/li\u003e\n\u003cli\u003eLoss of spark strength under load\u003c\/li\u003e\n\u003cli\u003eReduced fuel economy caused by weak ignition output\u003c\/li\u003e\n\u003cli\u003eCheck engine light concerns related to ignition coil failure\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch2\u003eInstallation Notes and Tips\u003c\/h2\u003e\u003cp\u003eVerify 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.\u003c\/p\u003e\u003ch2\u003eQuality Assurance\u003c\/h2\u003e\u003cp\u003eDelphi designs and endurance tests each ignition coil using quality materials and OE-based engineering.
