X4XZ Ignition Coil & Double Iridium Spark Plug Kit — 6-Coil/6-Plug for Acura & Honda 3.5L–3.7L Direct-Fit

X4XZ UF624 ignition coil pack kit with six 97390 double iridium spark plugs replaces OE 30520-RN0-A01 to restore reliable spark and smoother running for compatible Acura and Honda V6 engines.

This complete set pairs six high-quality ignition coils (UF624) with six double iridium spark plugs (97390 / E1124) engineered as direct-fit replacements for a range of 2009–2015 Acura and Honda 3.5L–3.7L models. Each coil and plug is built to match or exceed original specifications so you can regain proper ignition performance after misfires, rough idle, or reduced power. The kit emphasizes durable materials and noise suppression to help maintain stable firing and improved cold starts without complex modifications.

What vehicles and engine codes does this kit fit?

The X4XZ kit is matched to common V6 gasoline engines in select Acura and Honda model years. Fitment covers 2010–2013 Acura MDX 3.7L, 2013–2015 Acura RDX 3.5L, 2010–2013 Acura ZDX 3.7L, and many 2009–2015 Honda Pilot and 2009–2014 Honda Ridgeline 3.5L variants. Always cross-check part numbers and your VIN before purchasing.

• Replaces OE part numbers including 30520-RN0-A01 and UF624.
• Designed for 3.5L and 3.7L V6 engines listed in product details.
• See vehicle compatibility image (second main picture) for additional matches.

How do these coils and double iridium plugs improve ignition?

The ignition coils use premium thermoplastic connectors and internal ferrite noise suppressors to transfer high voltage consistently while limiting radio frequency interference. Double iridium plugs provide a finely machined firing tip for a stable, long-lasting spark, contributing to more reliable starts and steady idling.

• Double iridium electrode rated for extended life—consistent spark across mileage.
• Stainless-steel spring and ferrite suppressor reduce electrical noise and misfires.
• Thermoplastic connector resists heat-related cracking for secure fitment.

What symptoms indicate you should replace the ignition coil and spark plugs?

If you notice engine misfires, rough idle, reduced acceleration, or decreased fuel efficiency, worn coils or plugs are common culprits. Replacing both coils and plugs as a set helps restore balanced ignition timing and engine smoothness without trial-and-error part swaps.

• Intermittent or persistent engine misfire codes (check-engine light).
• Hard or slower-than-normal cold starts and rough idling.
• Lower fuel economy or hesitation during acceleration.
