LCWRGS Ignition Coil Pack Set for Honda Civic 1.7L (UF400) — 4-Pack, High-Energy Copper Windings

LCWRGS Set of 4 Ignition Coil Packs (UF400) is a direct-fit replacement for 2001–2005 Honda Civic and 2002–2004 Acura EL 1.7L engines, restoring reliable spark and smoother running.

If your Civic or Acura EL is showing misfires, reduced fuel economy, rough idling, or a persistent check engine light, worn ignition coils are a common culprit. These LCWRGS coil packs are engineered to meet or surpass original equipment specifications, offering higher energy output, robust materials, and an OEM-style fit that makes swap-outs straightforward for DIYers and technicians alike.

How do these coils improve engine performance?

Each LCWRGS coil is wound with highly conductive copper and potted in high-dielectric epoxy to reduce energy loss and resist heat-related breakdown. The design delivers up to an approximate 15% increase in energy output versus some OE coils, which can translate to crisper combustion and more consistent firing across cylinders.

• Higher-energy ignition for stronger spark and more complete combustion
• Durable epoxy potting to resist moisture and vibration
• Copper windings for improved conductivity and longevity

Are these coil packs compatible with my vehicle?

This set is specifically made to replace UF400 and other common OEM references on 2001–2005 Honda Civic 1.7L L4 and 2002–2004 Acura EL 1.7L models. They follow the original coil-pack footprint and electrical connectors so no modification is required for direct installation.

• Fits 2001–2005 Honda Civic with 1.7L L4 engines
• Fits 2002–2004 Acura EL 1.7L L4 engines
• Replaces UF400, C1460, 5C1451, E1012, E340, E420, 52-1789, IC520

How difficult is installation and what tools are needed?

Installation is typically a straightforward bolt-and-plug replacement following basic safety steps: disconnect the battery, remove the engine cover (if present), unplug the old coils, unbolt them, and reverse the process. No special programming or relearning is required in most cases—just ensure proper torque and connector seating.

• Basic tools: ratchet, socket set, and torque wrench recommended
• No ECU reprogramming required for direct-fit replacements
• Replace spark plugs if they are worn to ensure optimal performance

What kind of reliability and warranty do these coils offer?

LCWRGS coils are manufactured to meet or exceed OE build quality with materials chosen to withstand heat, vibration, and road contaminants. The product ships as a set of four and includes a 24-month warranty, plus customer support in case of fitment or quality questions.

• Set of 4 coil packs included for full-bank replacement
• 24-month limited warranty and customer support
