Ignition Coil UF652 and Iridium Spark Plugs 93815 Set of 4 - Reliable

In this review the set of four ignition coils UF652 paired with iridium spark plugs 93815 is evaluated for drivers of Hyundai Accent and Veloster, and Kia Rio and Soul models. The bottom line: this kit is for owners seeking a cost-effective, factory-fit replacement that improves start response and ignition reliability. The review finds the components well-built from specified materials, backed by a 12 month warranty and lifetime after-sales support, and particularly valuable when older cars show symptoms like rough idle, slow acceleration, or increased fuel use.

Key Features

• Vehicle compatibility: Fits Hyundai Accent 2012-2019, Veloster 2012-2017, and Kia Rio and Soul 2012-2019 so buyers can expect direct-fit replacements for those engines.
• Coil construction: Coil packs use silicon steel, Japan-imported rubber, and Germany-imported varnished wire for longer life and stable ignition performance.
• Spark plug technology: Iridium electrode and high-grade ceramic aim to deliver consistent spark, faster starts, and improved throttle response.
• OE cross-checks: Seller lists OE references such as UF652 and 93815 so buyers can verify fit before purchasing, reducing compatibility errors.
• Warranty and support: A 12 month warranty plus lifetime after-sales service provides added confidence after installation.

Who It's For

This kit is best for DIY mechanics and owners of the listed Hyundai and Kia models who need to replace worn coil packs and spark plugs, especially when symptoms include misfire, hard starting, or higher fuel consumption after roughly 50k-80k km of use. The included coils and plugs suit those who want a step up from worn OEM parts without a dealership price.

It is not the ideal choice for owners of vehicles outside the stated model years or those who cannot confirm OE numbers before buying. For performance-tuned engines or applications requiring bespoke ignition setups, a specialized aftermarket system would be more appropriate.
