NGK 49475 Ignition Coil

High-Performance Ignition Coil

NGK MOD ignition coil 49475 is a performance-grade COP ignition coil built for distributorless ignition systems. It is engineered for Audi and Volkswagen applications that need stable voltage delivery and consistent spark output under demanding conditions.

Key Features

• Coil-on-plug design for distributorless ignition systems
• Custom primary and secondary windings for increased output
• PET housing with vacuum-sealed epoxy resin for added insulation and durability
• High-temperature silicone COP boot for dielectric strength and voltage control
• Bolt-on mount with female connector and blade terminals
• 12-volt performance ignition coil, black finish

Detailed Description

NGK 49475 is part of the MOD high-performance ignition coil line, developed for enthusiast and performance vehicles. The coil uses a COP configuration with custom windings to support stronger output, while the PET housing, epoxy resin, and silicone boot help maintain insulation and durability in high-heat environments. This ignition coil is a direct fit for select Audi A4, A6 Quattro, S6, S8, RS6, TT, and Volkswagen Beetle, Passat, Golf, and Jetta applications listed in the fitment data. This part cross-references Standard Ignition UF-274 and Delphi GN10294 for the same application.

Common Replacement Issues

• Misfire under load
• Rough idle or hesitation
• Weak spark output
• Hard starting caused by ignition coil failure

Installation Notes and Quality

Verify the connector style, terminal layout, and bolt-on mounting points before installation. Confirm the vehicle uses a distributorless COP ignition system and match the part number 49475 to the application listing. NGK states these MOD coils are developed and tested in an ISO 17025 accredited lab for performance validation under extreme conditions, and they are engineered to work optimally with NGK spark plugs.
