NGK MOD Ignition Coil Set 6pk Stock #49467

The NGK MOD Ignition Coil Set 6pk (Stock #49467, MPN M5055-6) is a coil-on-plug pencil-style ignition system engineered for BMW vehicles from 2003 through 2022. This six-pack delivers the direct-fire ignition performance that modern BMW engine management systems demand, replacing worn or failing ignition coils that directly mount to the spark plugs. NGK's reputation for precision ignition components makes this set a specification-grade replacement for drivers seeking OEM-equivalent reliability.

Coil-on-plug design eliminates long secondary ignition leads, reducing electromagnetic interference and improving cold-start characteristics typical of BMW's inline-six and V8 engines across this generation. The black finish resists corrosion in engine bay environments where moisture and thermal cycling can degrade cheaper aftermarket coils. Each coil in the set carries NGK's engineering standards for consistent spark timing and energy output across all six cylinders, critical for maintaining fuel efficiency and emission control performance that BMW's onboard diagnostics expect.

This replacement set addresses a common wear item on higher-mileage BMW models, where individual coil failure often triggers check-engine codes (P0300-P0306 range). Replacing all six simultaneously ensures balanced ignition performance rather than a piecemeal approach that can mask underlying issues. Owners performing preventive maintenance or diagnosing misfire complaints benefit from having a complete, matched set rather than sourcing individual coils. The set's compact footprint and standard BMW connector configuration integrate directly into existing wiring harnesses without modification.
