KacuYelin Ignition Coil Pack & Iridium-Platinum Spark Plug Kit Set of 4 — UF802 for 1.4/1.5L Direct-Inject

KacuYelin UF802 coil pack plus four iridium-platinum spark plugs replace OE GN10797/91970 to restore reliable ignition for compatible 2016–2021 Chevy, GMC and Buick engines.

This kit combines four ignition coils engineered to match OEM electrical output with a set of long-life iridium-platinum spark plugs. It’s designed specifically for direct-injection 1.4L and 1.5L turbo engines found in selected Cruze, Equinox, Malibu, Terrain and Encore models from 2016 through 2021. The components are manufactured under TS16949-quality processes and aim to deliver consistent spark, improved durability and straightforward direct-fit installation.

Which vehicles and engines is this kit compatible with?

This set fits specific direct-injection turbo engines; it is not compatible with multi-port fuel injection variants. Confirm your vehicle year, model, engine displacement and injection type before ordering to ensure correct fitment.

• Chevrolet Cruze 2016–2019 1.4L (direct injection only)
• Chevrolet Equinox 2018–2021 1.5L
• Chevrolet Malibu 2016–2021 1.5L
• GMC Terrain 2018–2020 1.5L
• Buick Encore 2016–2019 1.4L (Sport Touring direct injection only)

How do the ignition coils and spark plugs improve engine performance?

The coil packs use high-purity copper windings and a silicon-steel core with heat-resistant epoxy to deliver steady high-voltage output, while the spark plugs use iridium-platinum construction and laser-welded electrodes for concentrated sparks. Together they restore cleaner combustion, which can translate to smoother starts and more consistent throttle response when installed correctly.

• Coils: corrosion-resistant materials and stable voltage delivery to reduce misfires
• Plugs: 360° laser welding and high platinum content for longer wear life
• Combined: optimized ignition timing and more complete fuel burn

What are the durability and service-life expectations for these parts?

The iridium-platinum spark plugs are built for extended service intervals and the coil construction emphasizes thermal and oxidative resistance. While individual results vary by driving conditions, the plugs are rated for extended mileage and the coils are designed to withstand high temperatures and typical engine stresses.

• Spark plug lifespan: engineered for long life, typically tens of thousands of miles
• Coil protection: high-temperature epoxy and quality core materials reduce degradation
• Manufacturing: produced in TS16949-certified facilities for consistent quality

How straightforward is installation and what should I check before buying?

The kit is manufactured to match OEM dimensions for direct plug-and-play replacement on compatible engines, making installation simple for a DIYer with basic tools or a professional mechanic. Before purchase, verify your car’s engine injection type and exact model year to avoid ordering an incompatible set.

• Pre-check: confirm direct injection vs. multi-port injection
• Fitment: enter Year, Brand, SubModel, Liter and Aspiration into fit-check tools
• Installation: replaces OEM UF802/12635672/GN10797/91970 numbered parts directly

Who is this for: This KacuYelin coil pack and spark plug kit is aimed at owners and technicians maintaining 2016–2021 Chevy, GMC and Buick small-displacement turbo engines that require direct-injection-compatible ignition parts. Choose this set if you want OEM-matching electrical performance, long-life iridium-platinum plugs, and a direct-replacement solution from a TS16949-certified manufacturer. If your vehicle uses multi-port injection, this kit is not suitable—double-check engine specs before ordering.
