Key Features

• Distributorless COP (coil near plug) design for modern ignition systems
• Custom primary and secondary windings for increased output
• PET housing with vacuum-sealed epoxy resin for insulation and durability
• High-temperature silicone boot for dielectric strength and voltage control
• Bolt-on mount type with female connector and blade terminals
• 12-volt performance-grade ignition coil

Detailed Description

NGK 49472 is part of the MOD High-Performance Ignition Coil Multi-Pack line, a product family aimed at enthusiast and performance use. The coil uses a coil-on-plug layout with engineered windings to improve output, while the housing, epoxy, and silicone boot materials are selected to support voltage insulation and long-term durability. NGK states these coils are developed and tested in an ISO 17025 accredited lab, and they are engineered for optimum performance when paired with NGK spark plugs. This part cross-references Standard Ignition UF-413 and Beck/Arnley 178-8411 for the same application.

What It Is Used For

• Misfire conditions caused by weak ignition output
• Rough idle related to inconsistent spark delivery
• Hard starting linked to ignition coil degradation
• Loss of throttle response from reduced coil performance
• Check engine lights triggered by ignition system faults

Installation Notes and Tips

Compatible with distributorless ignition systems that use a coil-on-plug layout. Verify connector style, terminal layout, and application notes before installation. Fits 2003-2020 Chevrolet Silverado, Chevrolet Tahoe, GMC Sierra, and related Cadillac, Buick, Pontiac, Saab, Hummer, and Isuzu applications listed in the fitment data. Part number 49472 should be matched to the vehicle’s original coil configuration and notes for proper application.
