Set of 4 UF400 Ignition Coil Pack and ZFR6FGP Spark Plugs Compatible

In this review the kit of four UF400 ignition coil packs and four ZFR6FGP spark plugs is evaluated for owners of Honda Civic and Acura EL 1.7L L4 models from 2001 to 2005. The bottom line: this is a practical replacement kit for drivers who need a straightforward, cost-effective way to address common ignition issues such as misfires, rough idle and poor fuel economy. The reviewer found the components durable in construction and effective at restoring stable ignition, making it a sensible buy for DIY mechanics and independent shops.

Key Features

• Multivehicle compatibility: Fits Honda Civic 2001-2005 and Acura EL 2001-2005 1.7L L4, simplifying parts selection for these specific models.
• Durable coil materials: Coil packs use silicon steel, a high-pressure rubber sleeve and epoxy resin to resist cracking and short circuits over time.
• Quality winding: Germany-imported venameled wire in the coils aims to provide consistent high-voltage output under a range of engine speeds.
• High-performance spark plugs: Iridium electrodes and isostatic ceramic insulators deliver quicker ignition and improved starting response versus standard plugs.
• OE fit and replacement numbers: Coil OE numbers listed for cross-reference, helping ensure correct replacement and fitment.
• Complete kit: Includes four coil packs, four spark plugs and a manual, giving a ready-to-install set for one engine.

Who It's For

This kit is aimed at Honda Civic and Acura EL owners with the 1.7L L4 engine from model years 2001 through 2005 who are experiencing ignition symptoms such as misfiring, stalling or poor idling and want a full-cylinder refresh. It is also well suited to DIY mechanics and independent repair shops looking for a single-purchase solution that includes both coils and plugs.

Those who should look elsewhere include owners with different engines or model years outside the listed compatibility, and drivers who prefer OEM-branded parts from a dealership for warranty or provenance reasons. Shoppers with unusual aftermarket engine modifications should verify fit before purchasing.

Pros & Cons

Pros

• Restores ignition stability and can resolve misfire and rough idle issues when coils or plugs are the cause.
• Coil construction materials and iridium spark plug electrodes suggest improved longevity and consistent performance.
• Complete set includes four coils and four plugs, making it convenient for a single-engine replacement.
• Generally positive feedback on functionality and value for money from customers.

Cons

• Some buyers reported fitment variability, so it may not be a perfect drop-in for every vehicle despite the listed compatibility.
• Not an OEM-branded kit, which could concern those who want factory parts or dealer support.
