NGK 49469 Ignition Coil

NGK MOD High-Performance Ignition Coil

The NGK MOD High-Performance Ignition Coil Multi-Pack is built for distributorless, coil-on-plug ignition systems that demand stable voltage delivery and consistent spark output. Designed for enthusiast and performance vehicles, this ignition coil uses upgraded winding design, durable housing materials, and high-temperature COP boots to support reliable ignition performance.

Compatible With select Ram, Dodge, Chrysler, and Jeep applications, this NGK ignition coil is engineered for vehicles such as the Ram 1500, Dodge Charger, and Jeep Grand Cherokee with twin spark ignition systems. Part number 49469 is also identified as M5121-8 in interchange listings.

Key Features

• 12-volt ignition coil for distributorless, coil-on-plug systems
• Performance-grade design for stable spark delivery
• Custom primary and secondary windings for optimized output
• PET housing with vacuum-sealed epoxy resin for insulation and durability
• High-temperature silicone COP boot for dielectric strength and heat resistance
• Female connector with 3 terminals and bolt-on mounting
• Silver finish

Product Details

NGK’s MOD High-Performance Ignition Coil line is developed for drivers who want a stronger, more consistent ignition component in demanding street and performance use. The coil’s winding design, insulated housing, and sealed construction are intended to maintain voltage control under heat and vibration. NGK also notes that these coils are engineered to work at their best when paired with NGK spark plugs. Part number 49469 is a direct reference point for this ignition coil family and is commonly searched alongside M5121-8.

This part cross-references Standard Ignition UF-504 and Delphi GN10352 for the same application.

Common Uses

• Misfire correction caused by weak or inconsistent coil output
• Rough idle related to ignition voltage loss
• Hard starting tied to worn coil-on-plug components
• Loss of throttle response from degraded ignition performance
• Heat-related ignition breakdown in distributorless systems

Installation Notes

Verify connector style, terminal count, and mounting points before installation. This coil uses a bolt-on mount with a female connector and is designed for COP applications, so the ignition boot must seat correctly on the spark plug. For best results, inspect spark plugs and related ignition components at the same time, especially on Ram 1500, Dodge Charger, and Jeep Grand Cherokee applications. Confirm vehicle-specific fitment by year, make, and model before ordering.

Quality Assurance

NGK develops and tests MOD ignition coils in an ISO 17025 accredited laboratory under severe operating conditions to validate performance and durability. The coil construction is focused on dielectric strength, voltage insulation, and long-term reliability in demanding ignition environments.
