LCWRGS Ignition Coil and Spark Plug Kit for Nissan Sentra 1.8L (2002–2006) — 4-Coil/4-Plug Direct-Fit

Complete ignition replacement kit: four LCWRGS ignition coil packs and four matching spark plugs engineered to restore reliable spark for Nissan Sentra 1.8L engines (2002–2006).

If your Sentra is showing misfires, rough idle, reduced fuel economy, or an illuminated check engine light, worn coils and plugs are a common cause. This LCWRGS kit bundles direct-fit ignition coils and compatible spark plugs that meet or exceed original equipment electrical and thermal specifications. The parts are designed for an easy swap with OE-style mounting and connections, so you can replace all four cylinders at once and get the engine firing cleanly again.

Will these parts fit my 2002–2006 Nissan Sentra 1.8L?

Yes — the kit is specified for the 1.8L L4 Sentra models from 2002 through 2006 and matches common OEM part numbers. It follows the direct OEM design for mounting, plug type, and electrical connectors, minimizing fitment issues during installation.

• Compatible model years: 2002, 2003, 2004, 2005, 2006 Nissan Sentra 1.8L L4
• Replaces OE numbers: UF351, C1397, E381, 5C1394, GN10245, 6734020
• Also cross-references: 224336N015, 2244800QAA coils and 4469 spark plugs
• Direct-fit design for factory mounting points and connectors

How will new LCWRGS coils and plugs affect engine performance?

Fresh coils and plugs restore consistent spark energy to each cylinder, which helps reduce misfires, improve throttle response, and stabilize idle. LCWRGS units are built to deliver reliable conductivity and higher dielectric performance compared with aged OEM parts.

• Improved ignition energy for cleaner combustion
• Reduced hesitation and fewer misfire codes
• Potential improvement in fuel efficiency and emissions stability
• Durable epoxy and copper conduction for longer service life

What does the kit include and is it easy to install?

The package contains four ignition coil packs and four spark plugs — everything needed to replace all cylinders on the 1.8L Sentra. Each coil uses a direct OEM-style connector and mounting flange, and the spark plugs are pre-gapped to typical specifications, simplifying do-it-yourself replacement or faster dealer/garage installation.

• Package: 4 coil packs + 4 spark plugs
• Pre-matched plugs and coils for correct cylinder placement
• OE-style fitment reduces the need for modifications
• Installation typically requires basic hand tools and 30–60 minutes per side

Are these LCWRGS components durable and reliable?

LCWRGS designs these ignition components to meet or exceed OE performance with high dielectric epoxy and conductive copper wire materials to support long-term reliability. While longevity depends on driving conditions and maintenance, the construction aims to resist heat and electrical degradation that cause premature failures.

• High-dielectric epoxy resists degradation under heat
• Copper conductive elements for efficient spark transfer
• Manufactured to match or improve upon original specifications
• Backed by customer support for installation and fitment questions

Who is this for: This LCWRGS ignition coil and spark plug set is for Nissan Sentra owners (2002–2006 1.8L) who want a straightforward, full-kit replacement to eliminate misfires and restore engine smoothness. It's suitable for DIY mechanics replacing all cylinders at once, independent shops needing a compatible aftermarket option, and drivers who prefer a comprehensive parts swap instead of piecemeal troubleshooting.
