Product Details

NGK’s MOD ignition coil line is developed for enthusiast and performance vehicles that demand reliable ignition under higher operating loads. The coil’s internal winding design is tuned to improve output, while the sealed housing materials help resist voltage leakage and environmental stress. NGK validates these coils in an ISO 17025 accredited test lab under severe operating conditions, and the design is intended to pair with NGK spark plugs for balanced ignition system performance. Part number 49471 is a direct search term for this NGK coil application.

This part cross-references Standard Ignition UF-414 and DENSO Auto Parts 673-7104 for the same application.

Common Symptoms This Coil Can Address

• Engine misfire under load
• Rough idle or inconsistent combustion
• Hard starting caused by weak spark output
• Loss of throttle response during acceleration
• Ignition breakdown from heat-related coil wear

Installation Notes and Tips

Verify connector style, terminal layout, and mounting points before installation. This coil uses a bolt-on mount with a female connector and blade terminals, so matching the OE configuration is important for proper fitment. For best results, inspect spark plugs and related ignition components at the same time, especially on Chevrolet Silverado 1500, GMC Sierra 1500, and Cadillac CTS applications. Confirm the vehicle’s exact year and engine configuration against the fitment list before ordering.

Quality Assurance

NGK develops and tests MOD ignition coils in an ISO 17025 accredited laboratory to evaluate performance and durability under demanding conditions.
