Ignition Coil Pack UF564 Replacement for 2006 Buick Lucerne - Set of 8

In this review the Ignition Coil Pack UF564 replacement is judged on fit, durability and ease of installation for V8 4.6L GM engines. The reviewer finds it most useful for owners of Buick Lucerne and several Cadillac models who need a straightforward drop-in solution to misfire or limp mode problems. The single biggest reason to buy is that these coils are built to be a direct replacement for OE part numbers such as UF564 and 12594176, delivering reliable ignition performance without the fuss of modification.

Key Features

• Direct Fitment: Compatible with Buick Lucerne and multiple Cadillac models so installation is typically plug-and-play for affected 4.6L V8 engines.
• OE Replacement Numbers: Replaces UF564, 12594176 and related part numbers so buyers can match their original equipment reference easily.
• Improved Efficiency: Designed with updated electronic control and precision manufacturing for roughly 10% better work efficiency compared with prior versions.
• Longer Service Life: Uses imported rubber rings and upgraded materials to provide about 15% more usage life and better resistance to complex road conditions.
• Set of Eight: Sold as a full pack, which is useful when multiple cylinders show misfire symptoms or for preventive maintenance on V8 engines.
• Support and Sustainability: Manufacturer promises 50,000 kilometers sustainability and direct support for issues or concerns.

Who It's For

This ignition coil pack is best for owners and mechanics working on 4.6L V8 GM vehicles who want a cost-effective replacement that matches original part numbers and restores engine smoothness. It suits people dealing with misfires, limp mode, or inconsistent idling who prefer a direct replacement rather than aftermarket rewiring or custom solutions.

It is less suitable for drivers whose vehicles use a different engine size or non-GM ignition systems, or for those seeking coils with specialized performance tuning beyond improved factory efficiency. If a single-cylinder coil is needed rather than a full eight-pack, buying individual units elsewhere may be more economical.
