LCWRGS Ignition Coil Pack Set for Honda Civic 1.7L L4 UF400 — Set of 4, OEM-fit with Copper Windings

The LCWRGS Set of 4 Ignition Coil Packs is a direct-fit replacement designed for 1.7L L4 engines in Honda Civic (2001–2005) and Acura EL (2002–2004). Built to meet or exceed original equipment standards, these coils use high-conductivity copper windings and advanced epoxy insulation to resist heat and electrical breakdown. Supplied as a complete set with a five-year warranty, they offer a straightforward swap to address misfires, rough idle, and poor fuel economy caused by degraded ignition components.

How do these coil packs match the original equipment?

LCWRGS coils follow the OEM geometry and electrical specifications so they fit without modification and work with existing wiring and connectors. Their materials and assembly are selected to mirror factory performance while delivering slightly higher energy output for improved ignition consistency.

• Direct OEM-style fit for 1.7L L4 engines (Honda Civic, Acura EL)
• Replaces part numbers UF400, C1460, 5C1451 and others
• Compatible with factory harnesses and mounting points
• High-conductivity copper windings and epoxy insulation

Will switching to LCWRGS coils improve drivability?

Replacing failing coils can reduce misfires, eliminate hesitation under load, and help the engine idle more smoothly. LCWRGS units are engineered to deliver a modest power/energy increase over aging coils, which can translate into steadier acceleration and fewer ignition faults.

• Up to roughly 15% more energy output than worn OE coils
• Helps reduce misfire-related fuel waste and rough idling
• Stabilizes spark timing across all cylinders
• May clear check-engine codes related to ignition faults

How simple is the installation process?

These coil packs are engineered for a straightforward, bolt-on replacement using standard hand tools; no special programming or adapters are required. Installers should follow basic safety and torque specs, and can swap coils one at a time to preserve firing order and simplify troubleshooting.

• Direct swap into original coil locations; no cutting or splicing
• Fits factory connectors and mounting points for quick replacement
• Recommended to replace all four coils to ensure balanced performance
• Basic tools and 30–60 minutes typical for DIY installation

Who is this for: This four-pack is intended for Honda Civic owners (2001–2005) and Acura EL drivers (2002–2004) with the 1.7L L4 engine who are experiencing misfires, rough idle, reduced fuel efficiency, or illuminated ignition-related trouble codes. It also suits mechanics and DIYers who prefer a complete set for consistent cylinder performance and a five-year warranty for added peace of mind. The LCWRGS coils are an economical, OEM-compatible option for restoring reliable spark delivery without modifying the vehicle's electrical system.
