KacuYelin Ignition Coil Pack & Iridium‑Platinum Spark Plug Kit UF802 Set of 4 — OE Fit, Better Starts

This KacuYelin UF802 kit pairs OE‑match ignition coil packs with durable iridium‑platinum spark plugs to replace worn ignition components on compatible Chevy, GMC and Buick models from 2016–2021. The coil windings and core materials are built for stable high‑voltage output while the spark plugs use advanced welding and high‑purity platinum for longer life and consistent combustion. The set is sold as a plug‑and‑play replacement that aligns with OEM dimensions and electrical characteristics—use your vehicle year, trim and engine type to confirm fit.

Which vehicles and engines will this set fit?

This kit is designed for specific GM models with direct injection 1.4L or 1.5L engines. It is not compatible with multi‑port/multi‑point fuel injection versions—confirm your engine type before ordering to avoid mismatches.

• Chevrolet: Cruze 2016–2019 (1.4L DI), Equinox 2018–2021 (1.5L), Malibu 2016–2021 (1.5L)
• GMC: Terrain 2018–2020 (1.5L)
• Buick: Encore 2016–2019 (1.4L DI) — Sport Touring trim only
• Replaces OE numbers: UF802, 12635672, GN10797, 91970, 12670053 (verify against your vehicle)

How do the ignition coils improve engine performance?

KacuYelin coils are constructed with high‑purity copper windings, a silicon steel core and heat‑resistant epoxy to maintain consistent high‑voltage output and resist corrosion. Stable voltage helps prevent misfires and reduces ignition failures that cause rough idle or poor acceleration.

• German‑import copper windings for efficient power transfer
• Silicon steel core for magnetic stability under load
• High‑temperature epoxy protection against heat cycling
• OE-equivalent fit and electrical specs for plug‑and‑play replacement

What makes the iridium‑platinum spark plugs last longer?

The spark plugs combine a 360° continuous laser welded center electrode and cold extrusion process to concentrate the spark and resist wear. High platinum content and premium alumina ceramic provide thermal stability and corrosion resistance for extended service life.

• Up to 90% platinum for abrasion and rust resistance
• 360° laser welding for focused, consistent sparks
• 95% alumina ceramic insulator for temperature tolerance and insulation
• Expected service life in higher range (approx. 70,000–100,000 miles under typical conditions)

Can this kit help fuel economy and emissions?

By restoring correct ignition timing and stronger, more reliable sparks, the set can improve combustion efficiency and reduce missed ignitions that increase fuel use and emissions. Exact gains depend on vehicle condition and driving habits; the product is designed to meet EPA‑relevant emission expectations when installed correctly.

• Improves ignition accuracy for more complete combustion
• May reduce fuel consumption increases caused by worn ignition parts
• Helps reduce common failures like hard starts and power loss
• OEM‑matching specs to maintain emissions control systems

Who is this for: The KacuYelin UF802 ignition coil and spark plug set is intended for owners and technicians maintaining mid‑2010s GM compact and midsize cars with direct injection 1.4L or 1.5L engines. Choose this kit if you want OEM‑style fitment, longer‑life plugs, and coils built for heat resistance and consistent high‑voltage performance. Always verify your vehicle’s year, engine code and fuel‑injection type before purchase to ensure compatibility.
