Product Details

NGK’s MOD high-performance ignition coil line is developed for drivers who want consistent ignition performance under demanding conditions. This coil is built for distributorless ignition systems and uses a coil-on-plug layout to deliver direct spark energy at the plug. The part number 49466 is also referenced as M5182-8 and is listed with interchange coverage including Delphi GN10164 and DENSO Auto Parts 673-6000 for the same application.

Compatible With Ford F-150, Mustang, Expedition, F-250 Super Duty, F-350 Super Duty, E-150, E-250, E-350 Super Duty, Crown Victoria, and Lincoln Town Car applications across the listed model years. It also covers Mercury Grand Marquis and Navigator fitments where specified in the vehicle data.

Common Problems This Part Can Address

• Misfire caused by weak ignition output
• Rough idle from inconsistent spark delivery
• Hard starting related to coil degradation
• Loss of throttle response under load
• Ignition performance issues in distributorless COP systems

Installation Notes and Tips

Verify connector style, terminal layout, and mounting configuration before installation. This coil uses a female connector, male terminals, and a bolt-on mount with one mounting hole. For best results, inspect spark plugs and replace worn plugs before installing the coil, especially on Ford F-150, Mustang, and E-350 Super Duty applications where ignition wear can affect coil performance.

NGK recommends pairing MOD ignition coils with NGK spark plugs for optimum system performance. 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 is built with high-temperature materials and insulation-focused construction to support reliable ignition performance in demanding use.
