UF413 Set of 8 Ignition Coils for V8 5.3L 6.0L - Fits Buick LaCrosse

In this review of the UF413 set of 8 ignition coils, the bottom line is simple: these coils are for owners of GM V8 5.3L and 6.0L vehicles who want a cost-effective way to restore engine smoothness without buying dealer parts. The reviewer found the pack useful for vehicles like Buick LaCrosse, Cadillac Escalade ESV, Chevrolet Avalanche and GMC Canyon when symptoms such as hard starting, misfires, or poor fuel economy appear after roughly 80,000 km. This review focuses on build quality, compatibility, and real-world effects on engine performance.

Key Features

• Japan and Germany materials: Rubber from Japan and varnished wire from Germany improve heat and abrasion resistance for longer coil life.
• Stable high-voltage output: Quality control aims to provide consistent spark energy to reduce misfires and improve throttle response.
• Wide vehicle compatibility: Designed to fit a range of GM V8s including Buick LaCrosse, Cadillac Escalade ESV, Chevrolet Camaro and GMC Yukon models.
• OE standard performance: Built to OE-grade durability and listed against common OE numbers for easier cross-referencing.
• Complete set of 8: Replacing all coils at once helps ensure balanced performance and avoids pairing new coils with aged units.

Who It's For

These ignition coils are best for DIYers and independent repair shops working on GM V8 5.3L and 6.0L engines who want an affordable full set replacement. They suit owners experiencing rough idle, misfires, long cranking times, or degraded fuel economy and who prefer replacing all coils together.

Those who should look elsewhere include drivers using non-GM engines or anyone needing guaranteed OEM brand warranty support from a dealership. Also, if corrosion problems have been prominent in a vehicle, further inspection of connectors and harnesses may be required in addition to new coils.

Pros & Cons

Pros

• Good materials and construction aimed at improved heat and corrosion resistance.
• Clear benefit to engine performance and drivability when aged coils cause misfires.
• Full set of eight simplifies installation and ensures uniform operation across cylinders.
• Competitive value compared with dealer-priced coil packs.

Cons

• Fitment varies by model year and specific engine variants, so double-check compatibility before purchase.
• Some customer reports mention corrosion on units over time, so monitoring connector condition is advisable.
