KacuYelin UF670 Ignition Coil Pack & Double Iridium Spark Plug Kit, 4‑pc for Ford/Lincoln 2.0–2.3L (2012–2021) OEM Fit

The KacuYelin UF670 kit combines four high-output ignition coil packs with four double‑iridium spark plugs engineered to restore reliable ignition and smoother running for compatible Ford, Lincoln and Jaguar 2.0–2.3L engines.

Designed as a direct-replacement ignition set, this package pairs precision coils with long‑life iridium plugs to help maintain consistent spark, improved throttle response and a cleaner burn across a range of 2012–2021 vehicles. Components meet OEM fit dimensions and are manufactured in TS16949 facilities using high‑purity materials, giving you plug‑and‑play installation without custom tuning.

Which vehicles will this UF670 ignition kit fit?

This kit is built for many 2.0L and 2.3L gasoline engines from Ford, Lincoln and certain Jaguar models; it excludes plug‑in hybrid (PHEV) and full hybrid (FHEV) variants. Always verify Year, Make, Model, Engine and Aspiration in the fitment tool before purchasing to avoid mismatch.

• Ford: Edge, Escape, Explorer, Focus, Fusion, Mustang, Taurus (selected years 2012–2021)
• Lincoln: MKC, MKT, MKZ (selected 2013–2019/2020 years)
• Jaguar: XE and XF 2.0L models (selected years)
• OE cross references: UF-670, UF670, UF729, UF678, GN10621, CM5Z12029K/A

How do the coil packs and double iridium plugs improve engine behavior?

The coils use high‑purity copper windings, silicon steel cores and heat‑resistant epoxy to deliver steady high‑voltage output and resist corrosion, while the double‑iridium plugs create a more focused spark for cleaner combustion. Together they reduce misfires and can help restore lost responsiveness on worn ignition systems.

• Stronger, more consistent spark from laser‑welded iridium electrodes
• Coils resist oxidation and thermal stress for steady voltage delivery
• Improved ignition accuracy under high RPM or turbocharged loads

What durability and performance specifics should I expect?

Iridium electrode content and a rigid ceramic insulator deliver extended plug life and stable insulation, while the coil materials mitigate electrical and thermal degradation. The manufacturer rates the plugs for long service intervals and highlights potential fuel‑efficiency improvements when replacing worn ignition components.

• Iridium electrode: up to 90% iridium, cold extrusion and 360° laser welding
• Ceramic insulator: high‑alumina composition for heat resistance and insulation
• Expected plug life: long service life up to tens of thousands of miles under normal conditions

Is installation plug‑and‑play, and are there special precautions?

Yes — the kit is designed to match OEM dimensions for straightforward replacement without modifications. However, confirm vehicle compatibility before installation and follow torque specs; avoid use on PHEV/FHEV models which aren't supported.

• Direct OEM-style fit for compatible models — no extra wiring or adapters
• Follow manufacturer torque and gap specs during plug installation
• Use the product fitment tool with full vehicle details to ensure correct selection

Who is this for: drivers and mechanics replacing worn ignition components on compatible Ford, Lincoln or Jaguar 2.0/2.3L gasoline engines who want long‑life plugs and robust coils without aftermarket tuning. It's ideal for routine maintenance, restoration of lost performance, or preventive replacement on vehicles experiencing misfires, rough idle, reduced throttle response or increased fuel usage. If you're unsure about fitment, provide your vehicle year, model and engine code before purchasing or contact KacuYelin customer support for assistance.
