SPARKWHIZ 8-Piece UF413 Ignition Coils, Platinum Spark Plugs & Wires Set – Chevy Silverado, GMC Compatible

Overview

The SPARKWHIZ Set of 8 Square UF413 Ignition Coils Pack & Platinum Spark Plugs & Wires is designed as a robust upgrade for modern engines. It combines high-discharge ignition coils with premium platinum plugs and durable wires to support a strong, consistent spark across a range of driving conditions. While not a guarantee, the components are chosen to work together for smoother starts, steadier idling, and more confident throttle response in everyday use.

What you get and why it matters

• Direct plug-and-play coils deliver greater discharge energy than stock coils, which can help promote a stronger spark and more reliable ignition under load.
• Premium parts include iridium spark plugs with a high melting point and a high spark generation rate, paired with 8mm OE-grade spark plug wires for durable, steady performance.
• Durable construction features German copper coils wrapped in polyester rubber, designed to withstand a range of driving conditions and temperatures.

Fitment and compatibility

This kit is positioned as an aftermarket upgrade for certain Cadillac, Hummer, Chevrolet, and GMC models. OEM PART NUMBERS include C1511, UF413, D510C, D513A, 5C1554, IC533, 12570616, 12611424, 8125706160, 331192, and 6737002. Always verify fitment against your vehicle’s specifications or the fitment bar before purchasing.

Installation tips

• We recommend applying a light spray of silicone on the coil during assembly to help prevent cracking of the rubber during disassembly.
• Use the original installation tools where possible to ensure a secure, confident fit.

Real-world scenarios

Envision steady starts on cold mornings, smooth acceleration on highway climbs, and consistent power delivery during hot-day commutes. These benefits can translate into a more predictable driving experience, especially for vehicles that rely on precise ignition timing for optimal performance.
