KacuYelin UF670 Ignition Coil Pack + 4 Double-Iridium Spark Plugs — Direct-Fit for Ford/Lincoln 2.0–2.3L (2012–2021), OEM-Style Du

KacuYelin UF670 ignition coil pack paired with four double-iridium spark plugs is a direct-fit replacement kit engineered to restore reliable spark and improve combustion for select Ford, Lincoln and Jaguar 2.0–2.3L engines (2012–2021).

This kit combines a durable UF670 coil pack built with high-purity copper windings and heat-resistant materials plus four double-iridium spark plugs designed for concentrated, long-lasting sparks. Together they aim to match OEM fitment and electrical characteristics so installation is plug-and-play on compatible models. The parts are produced in TS16949-certified facilities and replace OE numbers such as UF-670, UF729, UF678 and related Ford OEM references.

Which vehicles will this UF670 kit fit?

The set is intended for many Ford and Lincoln models with 2.0–2.3L gasoline engines and some Jaguar 2.0L applications from 2012–2021. It is not suitable for plug-in hybrid (PHEV) or full hybrid (FHEV) variants—always verify engine displacement and model year before purchase.

• Ford: Edge, Escape, Explorer, Focus, Fusion, Mustang, Taurus, Special Service Police Sedan (specific years/engines listed).
• Lincoln: MKC, MKT, MKZ compatible 2.0–2.3L gasoline engines.
• Jaguar: Selected XE and XF 2.0L gasoline models.

How do the coil pack and double-iridium plugs improve engine performance?

The coil pack provides consistent, high-voltage output thanks to quality copper windings and a silicon steel core, while the double-iridium plugs deliver concentrated, stable sparks and resist electrode wear. Together they help optimize combustion consistency and can reduce common ignition-related drivability issues.

• Smoother starts and fewer misfires by restoring steady spark delivery.
• Improved combustion efficiency—designed to help MPG and throttle response.
• Iridium electrode durability for extended service life (rated up to 80,000–120,000 miles).

What materials and manufacturing standards are used in this set?

The coil pack features German-imported high-purity copper windings, a silicon steel core and high-temperature epoxy for corrosion resistance and stable high-voltage output. The spark plugs use 360° continuous laser-welded iridium electrodes and high-alumina ceramic insulators for thermal stability and reliable insulation.

• Coil: copper windings, silicon steel core, heat-resistant epoxy.
• Plugs: 90% iridium electrode, 95% alumina ceramic body, laser welding.
• Manufactured in TS16949-certified facilities with R&D testing and quality control.

Is installation straightforward and what should I check before buying?

This kit is designed for direct fit and plug-and-play replacement when matched to the correct year, make, model and engine. Before ordering, use the vehicle year, brand, submodel, engine displacement and aspiration to confirm fitment, and be sure the vehicle is not a PHEV or FHEV variant if listed as incompatible.

• Plug-and-play when matched to the proper OEM spec and engine type.
• Confirm OE part numbers (UF-670, UF729, UF678 etc.) and vehicle details.
• If unsure, provide full VIN or vehicle details to the seller for confirmation.

Who is this for: This KacuYelin UF670 coil pack plus double-iridium spark plug kit is aimed at DIY mechanics, independent shops and fleet managers who need a reliable, OEM-compatible replacement for ignition components on compatible Ford, Lincoln and Jaguar 2.0–2.3L gasoline models from 2012–2021. It suits owners seeking improved ignition durability and more consistent combustion without changing engine tuning. If you operate a hybrid plug-in or FHEV vehicle, choose parts specified for hybrid systems instead.
