4PCS UF673 Ignition Coils + 4PCS 93618 Iridium Spark Plugs Pack

In this review the reviewer looks at a set of four ignition coil packs paired with iridium spark plugs that are marketed as replacements for UF-673 and 93618 fitments. The bottom line is that this pack is aimed at owners of 2012-2017 500 1.4L turbo and 2013-2016 Dart 1.4L turbo engines who need a cost-effective repair option; the single biggest reason to buy is the straightforward compatibility claim and the promise of improved starting and smoother running when a faulty coil is the cause of misfires and rough idle. The review focuses on real-world fit, ease of installation, and the practical benefits of fresh coils and iridium plugs for cold starts and fuel economy.

Key Features

• Set Compatibility: Sold as a set of four ignition coil packs and iridium spark plugs to match the four-cylinder layout commonly found in 1.4L turbo engines, simplifying replacement of all coils at once.
• OE Replacement Numbers: Designed to replace OE references such as UF-673, E1173 and 93618, which helps buyers confirm fit with common factory part numbers.
• Durable Spark Plug Thread: Uses an M12 thread diameter and 19 mm thread length on the plugs, providing a standard fit for the intended engines and secure seating in the cylinder head.
• Improved Driveability: Fresh coils supply consistent voltage to spark plug electrodes, which can reduce engine misfire, rough idle, and power loss compared with worn units.
• Simple Replacement: The coils are plug-and-play in many cases and customers report straightforward installation, making this a practical DIY option for mechanically inclined owners.
• Customer Support: The seller invites questions and promises to respond within 24 hours, offering aftermarket support if issues arise.

Who It's For

This pack is best for owners of the specified 1.4L turbo models who suspect ignition coil failure or are performing preventative maintenance on a vehicle with misfires, rough idle, or degraded cold-start performance. It is also suitable for DIY mechanics who prefer replacing all four coils at once to restore consistent spark output.

It is less appropriate for owners of vehicles outside the listed fitment or for those who require factory-branded OE parts; a few customers note fitment can differ on similar engines, so anyone with an uncommon variant should verify part numbers before buying.

Pros & Cons

Cons
