Detailed Description

NGK part number 49183 is a pencil-type ignition coil engineered for electronic ignition systems that use individual coils at each spark plug. This design supports direct spark delivery and is a common service part on Honda Civic, Honda Accord, Honda CR-V, Honda Insight, Honda Clarity, Acura RDX, and Acura TLX applications listed in the fitment data. If your vehicle is experiencing ignition misfire symptoms or inconsistent coil output, replacing the coil with the correct OE-style unit helps restore proper ignition performance.

This part cross-references Continental 49183 for the same application.

What It Is Used For

• Engine misfire caused by weak or failing coil output
• Rough idle related to ignition coil degradation
• Hard starting from inconsistent spark delivery
• Check engine light conditions tied to ignition system faults
• Loss of acceleration response caused by ignition breakdown under load

Installation Notes and Tips

• Verify the connector style, terminal count, and coil type before installation.
• Inspect the spark plug and coil boot area for oil, carbon tracking, or corrosion.
• Replace the coil only after confirming the vehicle uses a COP (pencil type) ignition setup.
• Clear diagnostic trouble codes after repair and confirm normal engine operation.
• Use the fitment data to match the exact Honda or Acura model and year before ordering.
