X4XZ Ignition Coil & Double Iridium Spark Plug Kit for 2013–2018 Mazda CX-5 — 4 Coils 4 Plugs OE-Fit, Long-Life

Complete replacement kit: four UF656 ignition coils plus four 93501 double-iridium spark plugs engineered to restore reliable ignition in compatible Mazda engines.

If your Mazda CX-5 (or other compatible Mazda models) is showing symptoms like rough idle, reduced power, or increased fuel consumption, worn ignition coils and spark plugs are common culprits. This X4XZ kit pairs OE-matching UF656 coils with long-life 93501 double iridium spark plugs to deliver a factory-style fit, stable spark delivery, and simplified installation for DIYers or professional technicians.

How will these coils and plugs affect engine starting and idle?

Replacing degraded ignition coils and plugs can significantly improve cold starts and smooth out idling. The coils transmit the high voltage needed for combustion while the double iridium plugs maintain consistent spark timing and longevity.

• Provides steady spark energy for quicker starts
• Reduces misfires that cause rough idle
• Double iridium electrodes last up to 100,000 km under normal conditions
• OE-equivalent connectors for reliable electrical contact

Will this X4XZ kit fit my Mazda CX-5 and other Mazda models?

The set is compatible with a range of Mazda vehicles that use the UF656 coil and 93501 plug part numbers. Always cross-check your vehicle’s year and engine with the product pictures or vehicle fit list before ordering to ensure correct fitment.

What are the build qualities and expected lifespan of the parts?

X4XZ combines durable coil construction with double iridium spark plug technology to balance performance and longevity. The coils include ferrite noise suppression and a thermoplastic connector, while the plugs use iridium tips that resist erosion for extended service life.

• Double iridium plugs: consistent performance, extended electrode life
• Stainless-steel spring and internal ferrite suppress radio interference
• Thermoplastic coil connector resists heat-related cracking
• Quality materials aim to match or improve OEM reliability

How easy is installation and what comes in the box?
