Upgrade Your 5.3L V8 with the ACCEntry UF414 Kit

This complete ignition upgrade pairs eight UF414 round ignition coils, eight double iridium spark plugs, and eight premium spark plug wires. Designed for a long list of GM vehicles, it fits many 5.3L/6.0L/6.2L V8 engines found in Chevrolet Silverado, Tahoe, Suburban, GMC Sierra, Yukon, Express vans, and more. The kit also covers models like Trailblazer, Avalanche, and Hummer H3 that share the same ignition layout. Before purchase, please review the fitment details and confirm your original coils are round in shape.

Why consider this upgrade?

Reliable spark is central to steady starts and smooth combustion. The UF414 coil pack is engineered to deliver consistent ignition energy, while the double iridium plugs provide durable performance under higher temperatures and prolonged use. Paired with robust spark plug wires, drivers may experience crisper cold starts, a steadier idle, and improved throttle response in everyday driving. Real-world results vary with vehicle condition, climate, and driving conditions, but the kit aims to support a more confident driving experience.
