Set of 4 UF652 Ignition Coil Pack and 93815 Spark Plugs 4 Pack

In this review the set of 4 UF652 ignition coil packs and 93815 spark plugs is evaluated for drivers who need a direct replacement kit for Hyundai and Kia 1.6L and some 2.0L engines. The bottom line: this kit is best for owners who want a full ignition refresh at once because it combines four coil packs and four iridium spark plugs that are built to meet OE form, fit and function, and aim to restore stable ignition and eliminate problems like misfires and check engine lights.

Key Features

• Direct compatibility: Designed to fit a range of Hyundai Accent, Veloster and Kia Rio and Soul model years listed, making a single purchase suitable for multiple 1.6L and select 2.0L applications.
• Durable coil construction: Coil packs use silicon steel, a high-pressure rubber sleeve, Japan-imported epoxy resin and Germany-imported venameled wire to resist cracking and short circuits over time.
• High-performance spark plugs: Spark plugs feature extremely fine iridium electrodes and isostatic ceramic insulators to improve ignition consistency and faster starts.
• Tested for reliability: Each coil and plug is subject to quality checks so the kit aims to reduce backfiring, misfiring, stalling and poor idling under normal operating conditions.
• Complete kit: The package includes four ignition coils, four spark plugs and a manual, which simplifies a full-cylinder ignition service in one purchase.

Who It's For

This kit is for do-it-yourself owners and independent mechanics who drive a compatible Hyundai Accent, Veloster or Kia Rio or Soul and need to replace all ignition coils and spark plugs at once to restore engine smoothness and fuel economy. It suits anyone who values parts that meet OE form and function and prefers a full set replacement rather than replacing single items piecemeal.

It is less appropriate for vehicles outside the listed model years or non-1.6L/2.0L engine variants; buyers who are unsure about fit should verify the vehicle compatibility picture or detail page before purchase to avoid size mismatch issues some customers have reported with plug fit.
