X4XZ Ignition Coil & Spark Plug Kit UF781 + 95660 4-Pack, Double‑Iridium Direct-Fit

X4XZ UF781 ignition coils paired with 95660 double-iridium spark plugs form a direct-fit ignition kit designed to restore reliable spark, smoother idle, and improved throttle response for compatible Honda and Acura 4-cylinder engines.

This complete four-pack replaces worn coils and spark plugs on a range of late-model Honda and Acura 1.5L and 2.0L turbo engines. Each ignition coil and plug is engineered to match or improve on the original equipment specifications, using double-iridium electrodes for long life and a thermoplastic coil connector plus an internal ferrite noise suppressor for stable high-voltage delivery. The kit comes ready to install: four UF781 coils and four 95660 double-iridium plugs, covering common OE part numbers for quick identification.

Which vehicles and engines does this X4XZ ignition kit fit?

The kit lists compatibility for many recent Honda and Acura models with 1.5L or 2.0L engines. It covers multiple model years and trims that use the UF781 coil and 95660 plug family, making it a practical replacement for routine maintenance or troubleshooting misfires.

• Honda Accord 2018–2021 (1.5L) and 2017–2021 (2.0L)
• Honda Civic 2016–2021 (1.5L) and 2018–2021 (2.0L)
• Honda CR-V 2017–2021 (1.5L) and 2020–2021 (2.0L)
• Acura TLX 2021 (2.0L) and Acura RDX 2019–2021 (2.0L)

How do these coils and double-iridium plugs improve daily driving?

Replacing old coils and plugs can eliminate rough idle, reduce misfires, and restore consistent combustion. Double-iridium plugs deliver a stable, long-lasting spark while coils with ferrite suppression reduce electrical noise and improve spark transfer to the plug.

• Smoother idle and fewer engine misfires
• Consistent spark under varied loads and temperatures
• Reduced radio frequency interference thanks to internal ferrite suppressor
• Long service life from iridium electrodes—rated for extended kilometers

What are the build and quality highlights of X4XZ UF781 coils and 95660 plugs?

Each UF781 coil uses robust materials and an advanced connector to resist thermal cycling and connector fractures. The 95660 spark plug uses double-iridium electrodes for wear resistance and stable firing characteristics across long service intervals.

• Stainless-steel spring and ferrite noise suppressor inside each coil
• Thermoplastic coil connector resists heat and vibration damage
• Double-iridium plug electrodes for long, consistent service life
• OE-equivalent fitment and part numbers for straightforward swapping

How easy is installation and what’s included in the package?

The kit is supplied with four UF781 coils and four 95660 double-iridium spark plugs to match the four-cylinder ignition layout. Installation is typically a bolt-and-plug swap for mechanics and experienced DIYers; no printed manual is included, so basic repair knowledge or a service guide is useful.

• Package: UF781 Ignition Coil x4, 95660 Double-Iridium Spark Plug x4
• Replaces OE numbers such as UF781, 49183, GN10886, 3052059B013, CM11-124A, and related codes
