X4XZ UF569 Ignition Coil and 12622561 Double Iridium Spark Plug Kit — 6-Coil/6-Plug V6 Replacement, Long-Life & Noise-Suppressed

X4XZ UF569 ignition coil and 12622561 double iridium spark plug kit delivers a direct replacement set of six coils and six long-life spark plugs engineered for compatible GM V6 engines.

This complete ignition pack from X4XZ pairs six UF569-style ignition coils with six 12622561 double iridium spark plugs to restore reliable spark, smoother idling and consistent combustion for many Buick, Cadillac and Chevrolet V6 models. Each component is built to meet or exceed original-equipment dimensions and connectivity so the kit installs quickly and integrates with your engine’s wiring and plug wells without modification. The double iridium electrode plugs are designed for longevity and stable firing, while the coils include noise suppression and durable connectors for repeated thermal cycles.

How will these ignition coils and plugs affect engine performance?

Replacing worn coils and plugs can reduce misfires, improve throttle response and help restore fuel economy that suffers from inconsistent ignition. This kit addresses both the high-voltage source (coils) and the spark interface (plugs), so it tackles common ignition-related drivability issues in one service.

• Six UF569-design coils engineered to fit OE mounting and connector locations
• Six double iridium plugs (12622561) for longer life and steady spark
• Internal ferrite suppressors in coils to limit radio interference
• Thermoplastic coil connectors resist heat-related cracking

Which vehicles are compatible with this X4XZ kit?

The kit is compatible with a broad list of GM vehicles equipped with the specified V6 engines across Buick, Cadillac and Chevrolet model years roughly from 2007–2019. Compatibility varies by engine displacement and year, so confirm fitment against your VIN or the vehicle list before purchasing.

• Buick: Enclave (2010–2018), LaCrosse (2010–2016) and related 3.0/3.6L variants
• Cadillac: ATS, CTS, SRX, STS and XTS V6 models (various years 2008–2019)

• See second product image or compare OE numbers (UF569, 12622561) for exact match

What are the construction and durability highlights of this ignition kit?

X4XZ builds the ignition coils with robust materials and noise suppression features while the plugs use a double iridium tip for extended service intervals. The kit focuses on longevity and consistent electrical performance under repeated heat cycles and engine vibration.

• Double iridium spark plugs rated for long service life and consistent spark
• Stainless-steel springs and internal ferrite suppressors reduce interference
• Premium thermoplastic connectors resistant to thermal cycling and fracture
• OE-replacement form factor to ensure proper seating and electrical contact

Who is this kit for? DIYers and professional technicians looking to replace all ignition coils and spark plugs at once will appreciate this X4XZ complete six-pack. It’s ideal when multiple misfires or rough-idle symptoms appear, when scheduled spark-plug service is due, or when you want matched coils and plugs for consistent engine timing across all cylinders. Confirm vehicle fitment and OE numbers (UF569, 12622561) before ordering; a full set of six coils and six plugs is included, but no installation manual is provided. X4XZ offers 24-hour customer support and a one-year product service window for post-purchase questions or issues.
