PHILTOP Ignition Coil Pack & Iridium Plug Kit, 4-Coil/4-Plug for 2010–2017 Chevy Equinox

PHILTOP UF491 is a complete ignition tune-up kit that includes four UF491 coil packs and four premium iridium 4513 spark plugs engineered to restore reliable spark and smoother engine performance. This kit is built as an exact-fit replacement for worn ignition components used on many GM 2.4L engines, including the 2010–2017 Chevy Equinox. Each coil pack and spark plug is matched to OE form and function so installation is straightforward and the parts work together to reduce misfires, improve throttle response, and help maintain steady idle and drivability.

How will this kit affect engine starting and idling?

Fresh coil packs and iridium plugs deliver stronger, more consistent spark energy, which typically leads to quicker starts and a smoother idle. Replacing aging ignition parts addresses intermittent misfires and unstable idling caused by weak spark or fouled plugs.

• Includes four UF491 coil packs matched to OE specifications
• Four 4513 iridium spark plugs resist fouling and maintain spark
• Helps reduce stalling and rough idle often linked to ignition wear

Will these parts fit my vehicle?

The kit is designed for GM 2.4L platforms and lists specific supported models for straightforward cross-referencing. Always verify compatibility with your VIN or OEM part numbers before purchase to ensure correct fitment.

• Common fitment: 2010–2017 Chevrolet Equinox 2.4L
• Also compatible with select Buick, GMC, Pontiac, Saab, Saturn, Fisker, and Chevrolet models listed by year
• Replaces OE coil and plug numbers such as 4513, UF491 and many equivalent references

What performance improvements can I expect after installing the kit?

Expect improved throttle response, fewer misfire codes, and more consistent power delivery under normal driving conditions. While results depend on the overall engine condition, replacing degraded ignition components is a common and cost-effective way to restore smooth operation.

• Reduces engine hesitation and hard-start symptoms
• Supports steadier acceleration and combustion efficiency
• Helps prevent misfire-related drivability issues

How difficult is installation and what should I prepare?

Installation follows OE location and mounting points, so a basic set of hand tools and standard mechanical experience are usually sufficient. If you’re replacing all coils and plugs at once, set aside about one to two hours and follow torque specs for spark plugs.

• Plug gap set and torque specs should match manufacturer recommendations
• Inspect wiring harness and boot seals while coils are removed
• Replace coils and plugs as a matched set for best results

Who is this for? This PHILTOP UF491 kit is aimed at DIY mechanics and professional technicians who need a matched set of ignition coils and iridium spark plugs for GM 2.4L engines—especially owners of 2010–2017 Chevy Equinox models looking to resolve misfires, rough idle, or diminished engine response without replacing individual components piecemeal. It’s also useful for fleet maintenance where consistent, OEM-style replacement parts are preferred.
