autoexact Ignition Coil Pack & Iridium Spark Plug Kit Set of 4 — OE Fit, Improved Throttle Response

Autoexact UF781 is a plug-and-play kit of four ignition coil packs and four iridium spark plugs engineered to restore reliable starts, reduce misfires, and improve throttle response for compatible Honda and Acura 1.5L/2.0L L4 engines.

Over time coils and spark plugs weaken, causing rough idles, poor fuel economy, or P0300–P0308 misfire codes. This Autoexact set combines epoxy-sealed ignition coils with fine-wire iridium plugs to provide hotter, more consistent sparks that help the engine burn fuel more completely. The components are manufactured to match OE fitment and arrive ready for straightforward DIY installation.

How will this kit affect drivability and fuel economy?

Replacing worn coils and plugs can immediately improve throttle response, smooth acceleration, and reduce hesitation under load. Better ignition consistency helps combustion efficiency, which often translates to modest fuel savings and fewer rough-idle episodes.

• Stronger spark for more complete combustion
• Reduced engine shake and smoother idle
• Improved throttle response under acceleration
• Iridium plugs rated for extended service life (up to ~40,000 miles)

Will these parts fit my Honda or Acura without modification?

This kit is designed as a direct OE replacement for specified model years and engine sizes—no cutting, splicing, or adapters required. Verify vehicle compatibility by checking model year and engine code before purchase to prevent fitment errors.

• Fits 2017–2023 Honda CR-V 1.5L
• Fits various 2016–2025 Honda Civic 1.5L / 2.0L applications
• Fits 2018–2021 Honda Accord 1.5L & 2.0L
• Fits 2019–2021 Acura RDX and 2021 Acura TLX 2.0L models

What should I know about installation and torque specs?

The kit comes factory pre-lubricated with dielectric grease and is intended for DIY replacement with common hand tools. Follow the recommended spark plug torque and use proper tightening sequence to avoid damage.

• Package includes: 4 ignition coil packs + 4 iridium spark plugs
• Recommended spark plug torque: 11.06–14.75 ft·lb (15–20 N·m)
• Factory-style connector and boot for plug-and-play swap
• Refer to the install guide on the product detail page

How durable are the coils and iridium plugs in this set?

Coils are epoxy-potted and heat-resistant to withstand ignition stresses; the iridium plugs use fine-wire electrodes for long life and stable firing characteristics. Each unit undergoes voltage and sealing tests and is backed by a limited warranty.

• Epoxy-sealed ignition coils for heat and moisture resistance
• Fine-wire iridium electrodes for extended service life
• Each part tested for voltage output and sealing integrity
• 2-year warranty plus lifetime expert support

Who is this for: Drivers and DIY mechanics who own compatible Honda or Acura L4 models and want a reliable OE-fit replacement set to resolve misfires, restore engine smoothness, and avoid costly dealership labor. It’s a practical upgrade for routine maintenance, performance recovery after aging ignition components, or preemptive servicing on higher-mileage vehicles.
