BELKEBIR Ignition Coil & Iridium Spark Plug Kit, Set of 4 for 1.4L/1.5L L4 (2016–2023) — OEM-fit, High-Energy

A plug-and-play repair kit of four BELKEBIR UF802 ignition coils and four iridium 91970 spark plugs designed to restore reliable ignition for 1.4L and 1.5L L4 Buick, Chevy, and GMC engines from 2016–2023.

Whether you’re troubleshooting misfires, rough idle, or a drop in fuel efficiency, this matched set of ignition coils and iridium spark plugs is built as a direct OEM-style replacement for common factory numbers including UF802 and 91970. Engineered to meet the electrical and dimensional specifications of original equipment, the kit aims to deliver consistent spark energy and long-lasting electrode life so your vehicle runs smoother after installation.

How do these BELKEBIR coils and plugs improve engine operation?

The coil packs deliver high-voltage, stable sparks while the iridium plugs maintain precise electrode gaps and resist wear. Together they help reduce misfires, improve throttle response, and support steady combustion across operating conditions.

• High-energy ignition coil output matched to factory specs for consistent firing.
• Iridium electrodes resist erosion for long service intervals and reliable starts.
• Balanced coil-plug pairing restores smoother idle and reduced stumble under load.

Which vehicles and part numbers are compatible with this set?

This kit is compatible with many GM compact and midsize models equipped with 1.4L or 1.5L L4 engines built between 2016 and 2023. It replaces OE and aftermarket part numbers so you can cross-reference before purchase.

• Covers 2016–2022 Buick Encore (1.4L L4) and 2016–2019 Chevy Cruze (1.4L L4).
• Fits Chevy Trax 2021–2022 (1.4L), Equinox 2018–2023 (1.5L), Malibu 2016–2023 (1.5L).
• Also compatible with 2016–2019 Chevy Volt (1.5L) and 2018–2023 GMC Terrain (1.5L).
• Replaces ignition coil numbers UF802, C2036, 12635672, 12670053, 12697989, 12698064, 25203537 and spark plug 91970.

What should I expect during installation and early use?

Installation is designed to be straightforward: these coils and plugs follow original-fit dimensions and connector layouts for a direct swap. You’ll typically notice improvements immediately after installation, though a short break-in period for the plugs is normal as electrodes seat and deposits stabilize.

• Plug-and-play connectors and OEM-style mounting make replacement fast for a DIYer or mechanic.
• Torque spark plugs to manufacturer specs and use anti-seize if recommended by your service manual.
• After installation, clear any stored trouble codes and test drive to confirm misfires and drivability issues are resolved.

How durable are these components and what maintenance is recommended?

BELKEBIR’s iridium plugs are made for longer service life than standard copper plugs, and the coils are constructed to withstand typical engine bay heat and vibration. Routine inspection during scheduled tune-ups helps ensure ongoing performance and prevents secondary issues.

• Iridium electrodes offer extended wear resistance versus standard plugs.
• Coil packs are sealed against moisture and vibration but should be inspected for cracked boots or corrosion.
• Replace as a set if multiple cylinders show wear or when diagnostic tests indicate coil failures.

Who is this for? This BELKEBIR four-coil and four-plug kit is intended for drivers and technicians who need a reliable, OEM-style replacement for ignition components on 1.4L and 1.5L GM L4 engines—especially owners of Buick Encore, Chevy Cruze, Trax, Equinox, Malibu, Volt, and GMC Terrain models from 2016–2023. It’s suited to DIY mechanics looking for a direct fit solution and service shops wanting a complete ignition refresh to address misfires, rough idle, or diminished performance without altering factory timing or engine management.
