Ignition Coil Pack UF680 with Iridium Spark Plug 94489 - Coil & Plug

In this review of the coil and plug kit, the bottom line is simple: this set is aimed at owners of compatible GM models who need a straightforward replacement for worn ignition components. The package combines four UF680 ignition coils and four iridium 94489 spark plugs, offering a single-purchase option for vehicles where misfires, rough idle, or sluggish acceleration point to aging coils and plugs. For those seeking an affordable rebuild of ignition performance, this kit provides a practical route to restore starting response and smoother running.

Key Features

• Complete replacement set: Includes four ignition coils and four iridium spark plugs to address all cylinders at once and simplify maintenance.
• Wide vehicle compatibility: Fits many GM models including Envision, Regal, ATS, CT6, CTS, Camaro, Equinox, Malibu, Traverse, and Terrain for the listed years, reducing fitment guesswork for owners of those cars.
• Durable coil construction: Coils are made with silicon steel, Japan-imported rubber, and Germany-imported varnished wire to improve longevity and thermal resistance.
• Iridium spark plug electrode: The plugs use an iridium electrode and engineered ceramic for reliable starts and improved throttle response.
• OE cross-reference: Coils and plugs reference common OE numbers so installers can verify fit using existing parts and service records.

Who It's For

This kit is best for owners and DIY mechanics of the listed GM vehicles who are experiencing symptoms like misfires, increased fuel consumption, rough idle, or slow acceleration, and who want to replace both coils and plugs together. It is also suitable for technicians looking for an economical multi-part service option to restore ignition performance without sourcing parts separately.

Drivers who do not see the exact OE numbers on their original parts or who need OEM-certified components for warranty reasons should look elsewhere. Also, if corrosion or previous electrical damage is suspected, a careful inspection is advised before installation to ensure the new coils will not be compromised.

Pros & Cons

Pros

• Restores engine performance and reduces misfires when parts are the root cause.
• Good value for a four-coil and four-plug kit compared with buying components separately.
• Reported ease of installation for most users who performed the swap themselves.

Cons

• Some customers reported fitment mismatches, so verifying OE numbers and vehicle compatibility is essential.
• A few reports noted corrosion and premature coil failure on older installations, indicating variable longevity in harsh environments.
