UF652 Ignition Coils & 93815 Iridium Spark Plugs Pack - Reliable

In this review the focus is on a practical replacement kit for 1.6L Hyundai and Kia engines: a set of four UF652 ignition coils paired with four 93815 iridium spark plugs. The bottom line is simple: this pack is for owners who need an affordable, direct-fit ignition solution to restore smooth running and eliminate misfire codes. The review shows why the combination of replaced OE numbers, thread specs and a matched coil-plus-plug approach makes this a sensible choice for routine maintenance or repair.

Key Features

• OE Replacement: The coils replace OE numbers UF652, 27301-2B100 and equivalents, giving buyers confidence about compatibility with listed Hyundai and Kia 1.6L models.
• Matched Spark Plugs: The included 93815 iridium plugs (SILZKR6B10E) provide durable electrode life and stable ignition for better combustion.
• Concrete Fit Data: Thread diameter M12 and thread length 26.5 mm are specified so installers can confirm mechanical fit before purchase.
• High Performance Design: The coils are described as premium quality with materials aimed at reliable ignition under varied conditions, reducing starting issues.
• Simple Replacement: Terminal quantity 2 and standard form factor make these coils straightforward to swap for mechanically inclined owners.

Who It's For

This kit is aimed at owners of 1.6L Hyundai Accent, Rio, Soul (2012-2019) and Veloster (2012-2017) who want a complete coil-and-plug replacement without sourcing parts separately. It is especially useful for drivers experiencing rough idle, misfire trouble codes or intermittent starting problems who prefer replacing all ignition items at once.

Those who should look elsewhere include owners of non-1.6L engines or vehicles outside the listed years, and anyone requiring OEM-branded parts or dealer-specific verification for warranty work. Always check the coil OE numbers and spark plug thread specs against your vehicle before purchasing.
