AULINK Ignition Coil Pack Kit UF620 with 4504 Spark Plugs — 4‑Pack for Chevy Cruze/Sonic/Trax, Tested & Heat‑Resistant

AULINK 4PCS UF620 ignition coil pack with matching 4504 spark plugs is a drop-in replacement kit engineered to restore reliable ignition for compatible Chevy and Pontiac 4-cylinder engines.

This kit combines four UF620 coil packs and four 4504 spark plugs to replace worn or failing ignition components on select Aveo, Cruze, Sonic, Trax and G3 models. Made in TS16949-certified facilities, the parts undergo full functional and leak testing. The coil housings are designed for heat and impact resistance while the spark plugs feature trivalent metal plating for corrosion protection. The set aims to deliver consistent spark performance and straightforward fitment using common OEM part numbers.

Which vehicle models will these coil packs and spark plugs fit?

These parts are matched to a range of small-displacement Chevrolet and Pontiac 4-cylinder models. Confirm compatibility by matching your vehicle year, engine size and original part numbers before ordering.

• Chevrolet Aveo / Aveo5 1.6L (2009–2011)

How do these UF620 coils and 4504 plugs perform under heat and stress?

The coil packs are built using materials and assembly methods that tolerate elevated under-hood temperatures and vibration. Spark plugs are trivalent metal plated to reduce corrosion risk and maintain a stable electrode surface, supporting consistent firing over time.

• High-temperature resistant coil housing reduces thermal degradation
• Impact-resistant construction to withstand engine vibration
• Trivalent plating on plugs for improved corrosion protection
• Each unit is function and leakage tested during production
