Common Problems This Part Can Address

• Misfire caused by weak or inconsistent ignition output
• Hard starting related to ignition coil failure
• Rough idle from unstable spark delivery
• Loss of power under load due to ignition breakdown
• Check engine light conditions tied to ignition coil faults

Installation Notes and Tips

Verify the connector style, terminal layout, and mounting-hole pattern before installation. This ignition coil uses a 4 male pin sealed connector and blade terminals, so matching the original electrical interface is important for proper fitment. Confirm the vehicle’s exact year, engine setup, and connector orientation, especially on 1998-2000 Ford Ranger and 1998-2000 Mazda B3000 applications with a horizontal connector.

Quality Assurance

Delphi builds aftermarket parts using more than a century of OE experience and supplier knowledge gained from working with major automakers. That OE heritage is reflected in the design and construction approach behind GN10178.
