Our review of the UF652 ignition coil and 93815 iridium spark plug set finds it best suited for owners who need a direct replacement for 1.6L Hyundai and Kia engines. The bottom line: this set replaces four coils and plugs with parts that mirror OE design and focus on durability and consistent spark delivery, which helps resolve common issues like misfires and rough idle. For drivers of Hyundai Accent, Veloster, Kia Rio or Soul with 1.6L engines, this kit targets improving cold starts, smoother acceleration, and better fuel efficiency.

Key Features

• Wide compatibility: Covers Hyundai Accent 1.6 (2012-2020), Veloster 1.6 (2012-2017), Kia Rio 1.6 (2012-2019) and Kia Soul 1.6 (2012-2019), simplifying part selection for these models.
• Durable ignition coils: Coils are built from premium materials with an advanced thermoplastic connector to ensure a secure fit and reliable high-voltage transfer to the spark plug.
• Noise suppression: Stainless-steel spring with an internal noise suppressor reduces radio frequency interference that can accompany ignition components.
• Iridium spark plugs: Plugs are specified to last 100,000+ kilometers, offering stable sparks for improved cold starts and smoother throttle response.
• OE-fit replacement: Components are designed to match or improve on OE geometry so installation is straightforward and compatibility with factory systems is maintained.

Who It's For

This set is ideal for DIY mechanics and independent shops servicing 1.6L Hyundai and Kia compact cars that are experiencing misfires, rough idle, decreased power or poor fuel economy due to worn coils or plugs. It suits owners who prefer replacing all four ignition assemblies at once to restore consistent performance.

It is less appropriate for vehicles outside the listed model years or for owners who require dealer-branded OEM parts for warranty or certification reasons; buyers should verify fitment using the provided vehicle reference image before purchase.

Pros & Cons

Pros

• Direct-fit parts that aim to match OE design for easier installation and reliable operation.
• Iridium plugs offer long life and more consistent spark, which helps fuel efficiency and cold starts.
• Coils include an internal noise suppressor and robust materials to improve longevity and reduce interference.

Cons

• Fitment is specific to listed 1.6L models and years, so confirming compatibility is necessary before purchase.
• The listing focuses on materials and fit rather than detailed durability testing data, so long-term performance depends on installation and vehicle conditions.
