Delphi GN10291 Ignition Coil

Delphi GN10291 Ignition Coil Overview

The Delphi GN10291 ignition coil is a conventional replacement coil built for older ignition systems that use a blade-style, 2-terminal male connection. It draws on Delphi’s OE heritage and supplier experience to deliver a direct-fit ignition coil for select Nissan and Isuzu applications, including Nissan 200SX, 300ZX, Maxima, Sentra, 720, Pulsar NX, and Isuzu Pickup, Trooper, and Amigo.

Use this ignition coil when you need a dependable OE-style replacement for a vehicle that is experiencing weak spark, misfire symptoms, or hard starting. The Delphi GN10291 is also cross-referenced to Denso 5031 for the same application.

Detailed Product Description

The Delphi GN10291 ignition coil is engineered for vehicles that require a conventional coil configuration rather than a coil-on-plug design. Its blade terminal layout and male terminal gender support the factory-style electrical connection used on the listed applications.

Delphi builds aftermarket parts with knowledge gained from supplying original equipment to major automakers, and that background is reflected in the GN10291’s fitment-focused design. The part number GN10291 is also commonly referenced in interchange listings for related ignition service parts, helping simplify cross-checking during repair planning.
