LCWRGS Ignition Coil Pack Set for Honda Civic 1.7L (UF400) — 4-Pack Direct-Fit, High-Conductivity Copper

LCWRGS Set of 4 ignition coil packs (UF400) are a direct-fit replacement designed to restore reliable spark and ignition performance in 2001–2005 Honda Civic and 2002–2004 Acura EL 1.7L L4 engines.

These four coil packs are manufactured to meet or surpass original equipment specifications so they plug directly into the factory harness and mounting points without modification. Built with high-conductivity copper windings and high-dielectric epoxy encapsulation, the LCWRGS coils prioritize long-term electrical stability and resistance to heat and vibration. The set replaces common OEM numbers such as UF400, C1460, and IC520, offering an affordable route to clear misfires, reduce hesitation, and improve throttle response when the original coils start to fail.

How will these coils affect everyday drivability?

Replacing worn or failing ignition coils can noticeably smooth engine operation under typical driving conditions. You should expect fewer misfires, more consistent idling, and steadier acceleration as each cylinder receives a stronger, more reliable spark.

• Restores even combustion across all four cylinders
• Reduces rough idle and intermittent stalling
• Improves throttle response and drivability under load

Are these coil packs easy to install on a Civic 1.7L?

Yes — LCWRGS coils are engineered as direct OEM-fit replacements so no cutting, splicing, or special programming is required. Most DIYers with basic hand tools can swap all four packs in under an hour by following a service manual or online guide for your model year.

• Direct-fit design matches factory mounting and connectors
• No ECU reprogramming needed — plug-and-play installation
• Includes four coils so you replace the set for balanced performance

What makes LCWRGS coils different from worn OE coils?

LCWRGS coils use upgraded copper winding and enhanced epoxy sealing to maintain conductivity and resist moisture ingress and heat breakdown. The manufacturer states increased energy output compared with aged OE units, which helps maintain spark intensity over the coil’s service life.

• Higher-conductivity copper for efficient current transfer
• High-dielectric epoxy reduces internal arcing and moisture damage
• Engineered to meet or exceed original specifications for durability

Which vehicles and OEM part numbers are compatible?

This four-pack fits 2001–2005 Honda Civic models with the 1.7L L4 engine and 2002–2004 Acura EL 1.7L L4. It is intended to replace OEM references so you can match replacement needs to the numbers on your failed coil.

• Compatible years: Civic 2001, 2002, 2003, 2004, 2005; Acura EL 2002–2004
• Replaces OEM numbers: UF400, C1460, 5C1451, E1012, E340, E420, 52-1789, IC520
• Sold as a complete set of four ignition coil packs

Who is this for: This replacement set is ideal for Honda Civic and Acura EL owners experiencing misfires, rough idle, decreased performance, or a check-engine light that traces to ignition coils. Mechanics and home DIYers who prefer plug-and-play, OE-equivalent parts will appreciate the direct-fit design and the convenience of replacing all four coils at once. The product includes a five-year warranty, providing added confidence for drivers who want dependable, long-term ignition performance without upgrading other engine components.
