Product Details

NGK ignition coils are developed for OE-level fit and performance, with testing performed in an ISO 17025 accredited lab under demanding conditions. The NGK COP Ignition Coil line is built for late-model domestic and import coverage, and this application-specific unit supports Nissan Sentra ignition service where a coil-on-plug replacement is required. If you are replacing a failing ignition coil on a 2002-2006 Nissan Sentra, part number 49008 provides a direct replacement path for the listed applications.

This part cross-references Delphi GN10245 and Standard Ignition UF-351 for the same application.

Common Problems This Part Can Address

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

Installation Notes

Verify the vehicle’s year, engine configuration, and Federal Emission System coverage before installation. Confirm the connector style, terminal count, and coil-on-plug layout match the original unit on the vehicle. Inspect the spark plug and coil boot area for oil, corrosion, or carbon tracking before installing the new coil. For best results, replace any damaged connectors or worn spark plugs that could affect ignition performance.
