4PCS UF802 Ignition Coils + 4PCS 91970 Iridium Spark Plugs Pack - Coil

In this review the focus is on a combined ignition coil and spark plug pack aimed at owners of select small-displacement GM sedans and crossovers. The kit includes four UF802-style ignition coils and four NGK 91970 iridium spark plugs, and the single biggest reason to consider it is the straightforward way it replaces worn ignition components to restore engine smoothness and starting reliability. It is best suited to do-it-yourselfers and independent shops who need a complete coil-pack swap for 1.4L and 1.5L models and want a matched set rather than sourcing parts separately.

Key Features

• Direct replacement compatibility: The pack uses OE numbers UF-802 UF802 C2036 12635672 12670053 and NGK91970 so it is intended to fit the listed Equinox, Cruze and Malibu engines without major modification.
• Complete four-cylinder kit: Including four coils and four iridium spark plugs means all cylinders are serviced at once, helping restore balanced ignition and smoother idle.
• Iridium spark plugs: The NGK 91970 plugs offer the longer life and stable sparking characteristics expected from iridium electrodes, which can improve throttle response and efficiency.
• Compact coil dimensions: Coils with M12 thread diameter and 25mm thread length are sized for the target engines and simplify installation when replacing OEM units.
• Durability focus: The coils claim premium construction and long service life so they can operate under a variety of conditions without early failure.
• Aftermarket value: Buying the matched coil and plug set removes guesswork and often costs less than purchasing branded OEM components separately.

Who It's For

This kit is for owners of 2018-2020 Equinox, 2016-2019 Cruze, and 2016-2020 Malibu models equipped with 1.4L or 1.5L engines who want a full ignition refresh. It is particularly useful for technicians and DIYers who prefer to replace all coils and plugs at once to address misfires, rough idle, or poor starting.

It is not for vehicles outside the listed compatibility or for owners who require dealer-branded OEM parts for warranty or service-record reasons. Buyers should also verify the spark plug thread diameter and thread length against their engine before purchasing to avoid fitment issues.

Pros & Cons

Pros

• Includes a matched set of four coils and four iridium plugs for consistent ignition performance across cylinders.
• Replaces known OE numbers and uses common coil dimensions for the targeted GM engines.
• Customers report improved engine smoothness and good value for the price.

Cons

• Some buyers may encounter fitment differences on non-listed models, so exact compatibility must be checked beforehand.

Specifications
