This part cross-references DENSO Auto Parts 673-4023 and Standard Ignition UF-349 for the same application.

What It Helps Address

• Engine misfire caused by a weak or failed ignition coil
• Rough idle during startup or at operating temperature
• Hard starting related to inconsistent spark output
• Loss of acceleration response from ignition breakdown
• Check engine light conditions tied to ignition coil faults

Installation Notes

Verify connector style, terminal count, and engine application before installation. This coil uses a distributorless COP layout and is intended for vehicles listed in the fitment data, including 2002-2006 Nissan Altima, 2005-2019 Nissan Frontier, 2002-2007 Nissan Maxima, 2003-2007 Nissan Murano, 2002-2012 Nissan Pathfinder, and 2002-2004 INFINITI I35. Confirm the exact model year and build date where notes apply, such as 2008 Nissan Maxima to 5/2008 and 2001 INFINITI QX4 from 07/2001.

For best results, inspect the coil connector, spark plug condition, and related ignition components during service. The part number 48845 should be matched to the vehicle’s original coil configuration before installation.

Quality Assurance

NGK manufactures ignition coils to meet or exceed OE standards and validates designs in an ISO 17025 accredited test lab under demanding conditions. That testing approach supports consistent durability and operational performance across the listed Nissan, Infiniti, and Suzuki applications.
