In this review of the 4PCS UF764 ignition coils plus 4PCS 93175 iridium spark plugs pack, the bottom line is simple: it is a practical, cost-conscious replacement for owners of compatible 2.0L and 2.4L Hyundai and Kia models who need reliable ignition performance. The reviewer found the set delivers improved engine starting and smoother running while offering good value. This review focuses on fit, durability, and installation experience so buyers can decide if the pack meets their maintenance needs.

Key Features

• OE Compatibility: The set replaces OE numbers UF764 and 27300-2GGA0, making it suitable for direct replacement in many Hyundai and Kia engines.
• Spark Plug Specification: The included iridium spark plugs match NGK 93175 sizing with M12 thread diameter and 26.5 mm thread length for consistent ignition gaps.
• Four-Cylinder Coverage: With four ignition coils and four spark plugs, the pack services an entire 4-cylinder ignition bank at once, simplifying maintenance.
• Durability: Premium materials and design are claimed to provide long service life and reliable performance across varied operating conditions.
• Installation Friendly: Customers report the coils and plugs install cleanly and fit properly, reducing shop time for routine replacement.

Who It's For

This pack is aimed at DIYers and independent shops working on Hyundai Sonata, Santa Fe, Tucson and Kia Optima, Sorento, Sportage and similar models with 2.0L or 2.4L engines that list UF764 or 27300-2GGA0 as compatible coil or NGK 93175 spark plugs. It is a good choice for owners who want to replace the entire ignition set at once rather than changing coils and plugs individually.

Those who should look elsewhere include owners of engines with different coil or spark plug specifications, or anyone who requires manufacturer-branded parts or an original-equipment warranty from their dealer. Also double-check vehicle fitment before ordering to avoid receiving incorrect spark plugs.
