BDFHYK Ignition Coil Pack & Iridium Spark Plug Kit for Honda Civic 2001-2005 1.7L — Set of 4 UF400/ZFR6FGP

Complete replacement kit of four BDFHYK ignition coils (UF400) paired with iridium ZFR6FGP spark plugs, engineered to fit 2001–2005 Honda Civic 1.7L L4 engines.

If your 2001–2005 Honda Civic with the 1.7L L4 engine is showing rough idling, slow throttle response, difficulty starting, or increased fuel use, worn coil packs and spark plugs are common culprits. This BDFHYK set bundles four high-quality ignition coils and matching iridium spark plugs to restore consistent spark delivery and revitalize combustion performance. Each coil is manufactured using durable materials like silicon steel cores, premium rubber components, and varnished windings for long life, while the iridium-plated electrodes and advanced ceramic insulators in the ZFR6FGP plugs are designed for stable ignition and improved durability over standard plugs.

Will this kit fit my Honda Civic 2001–2005 1.7L L4?

Compatibility targets the Civic 2001–2005 with the 1.7L L4 engine, but fitment should always be confirmed against your vehicle’s OE numbers. Compare the OE references in the product details (for example UF400 and ZFR6FGP equivalents) with your current parts or service manual before installation.

• Designed for 2001–2005 Honda Civic 1.7L L4 engines.
• OE cross-reference provided (UF400, 30520-P8E-A00 and others).
• Verify part numbers before purchase to ensure correct match.

How do these ignition coils and plugs improve engine performance?

The coils supply a consistent, high-voltage spark to each cylinder while the iridium plugs provide precise, long-lasting electrodes for better combustion. Together they reduce misfires, stabilize idle, and help the engine respond more quickly to throttle inputs without promising specific mileage or power gains.

• Coils use robust materials and varnished windings for reliable spark generation.
• Iridium electrodes resist wear for more consistent ignition over time.
• Reduced misfires and smoother throttle response when properly installed.

What are the build quality and lifespan expectations for these parts?

BDFHYK coils are built with silicon steel cores and premium rubbers, and the plugs use high-tech iridium and ceramic, which typically extend service life versus basic replacements. Actual lifespan depends on driving conditions and maintenance, but materials and construction aim to provide durable operation under typical use.

• Coils use imported materials for improved longevity.
• Iridium plugs designed for extended electrode life compared to standard plugs.
• Package includes basic installation guidance; professional fitting recommended if unsure.

Who this kit is for: This BDFHYK coil-and-plug kit is for Honda Civic owners (2001–2005, 1.7L L4) who want a full ignition-service replacement in one purchase—especially cars showing rough idle, sluggish acceleration, or frequent misfires. It’s suitable for DIY enthusiasts comfortable with basic engine work and for independent shops seeking a matched coil-and-plug solution. Always confirm OE compatibility before buying; if your vehicle has more than 80,000 km and shows related symptoms, this kit is a logical maintenance or repair option.
