KacuYelin UF582 Ignition Coil Pack and Iridium Spark Plug Kit for Honda Civic 2006-2011 1.8L — Set of 4, OEM Fit & Durable High-Te

Complete ignition kit: four KacuYelin UF582 coil packs paired with four iridium spark plugs engineered to replace OE 30520-RNA-A01 and fit Honda Civic 2006–2011 1.8L engines.

This kit combines robust ignition coils and high-performance iridium spark plugs made to match OEM fit and function for Honda Civic 1.8L model years 2006 through 2011. Each coil uses high-purity copper windings, a silicon-steel core and heat-resistant epoxy for reliable high-voltage output, while the iridium plugs employ laser-welded center electrodes and high-alumina ceramic insulation to deliver steady sparks, better combustion and long service life.

How do these coil packs and iridium plugs improve my Civic's ignition reliability?

The coil packs are built with premium copper windings and corrosion-resistant materials to sustain consistent voltage delivery under thermal stress, which reduces misfires and ignition-related starting issues. The iridium plugs maintain a focused spark pattern for more complete combustion and longer service life than standard nickel plugs.

• Direct-fit replacement for OE numbers like 30520RNAA01 and UF-582.
• High-temperature epoxy and silicon-steel core for stable voltage output.
• Laser-welded iridium electrode for concentrated sparks and durability.
• Designed to lower misfires and reduce carbon deposits over time.

Will this set affect fuel economy or emissions?

Improved ignition consistency promotes more complete fuel combustion, which can reduce unburned fuel and lower exhaust emissions. KacuYelin reports optimized engine performance and fuel efficiency gains when ignition components are refreshed, though actual results depend on vehicle condition and driving habits.

• Optimized spark timing leads to more efficient combustion.
• Potential MPG improvement from cleaner burn and reduced misfires.
• Reduced carbon buildup contributes to steadier long-term performance.

Are these parts easy to install and compatible with my Civic?

Yes—this coil-and-plug kit is manufactured to OEM dimensions for a plug-and-play swap on compatible Civic 1.8L models. Installation requires basic hand tools and follows the same mounting and electrical connectors as the original parts, but always verify fit with your exact year and submodel before purchase.

• Plug-and-play design matching OEM specifications (30520-RNA-A01, etc.).
• Compatible with Honda Civic 2006–2011 1.8L engines—confirm year and submodel.
• Standard hand tools and basic mechanical knowledge needed for swap.

What materials and manufacturing standards back performance and longevity?

KacuYelin produces these components in TS16949-certified facilities using high-grade materials: copper windings for the coils, high-alumina ceramic for plug insulation and iridium/nickel alloy electrodes for wear resistance. The company emphasizes testing and quality controls intended to meet or closely match OEM durability and electrical characteristics.

• German-imported high-purity copper for efficient power transmission.
• High-alumina (≈95%) ceramic insulators for heat resistance and insulation.
• Iridium center electrodes with up to 90% nickel content for longevity.
• Manufactured in TS16949-certified production lines with R&D testing.

Who is this for: This KacuYelin UF582 coil pack and iridium spark plug kit is aimed at Honda Civic owners (2006–2011, 1.8L) who want a complete ignition refresh to restore smooth starts, reduce misfires and maintain efficient combustion. It suits DIY mechanics replacing worn ignition parts as well as service shops seeking a ready-made, OEM-compatible replacement set. Before purchasing, confirm your vehicle's year, engine size and submodel to ensure proper fitment.
