autoexact Ignition Coil and Iridium Spark Plug Kit for Honda Civic 2.0L / Fit 1.5L, 4-Pack — Direct OE Fit, Pre-Gapped Plugs

Complete ignition coil and iridium spark plug kit engineered to replace worn units and restore smooth starts, stable idling, and improved combustion for compatible Honda Civic and Fit engines.

This kit from autoexact pairs four epoxy-potted ignition coil packs with four pre-gapped fine-wire iridium spark plugs to deliver consistent spark energy and longer plug life than standard parts. Designed as a direct, no-modification replacement for specific Honda Civic (2016–2021 2.0L non-turbo) and Honda Fit (2015–2019 1.5L) models, the set is intended for drivers wanting to correct misfires, rough idle, or reduced fuel efficiency caused by aging ignition components.

How will these coils and iridium plugs affect engine performance?

Replacing degraded coils and plugs renews the ignition system’s ability to produce a stronger, more stable spark. That helps the air–fuel mixture burn more completely, which can improve throttle response and reduce hesitation under acceleration.

• Higher ignition energy from epoxy-sealed coils for consistent firing.
• Fine-wire iridium tips pre-gapped for reliable combustion and longer life.
• Reduced misfire codes (P0300–P0308) when worn parts are the root cause.
• Smoother idle and quieter engine operation after installation.

Are these parts easy to install for a home mechanic?

Yes — the kit is made for direct replacement with an OE-style fit so no cutting or adapters are required. Basic hand tools and standard torque control are sufficient for most DIYers comfortable working in the engine bay.

• Factory-style fitment reduces alignment and mounting issues.
• Plugs arrive pre-gapped; coils pre-lubricated with green dielectric grease.
• Recommended torque: 11.06–14.75 ft·lb (15–20 N·m) for spark plugs.
• Install guide available on the product page for step-by-step help.

Which vehicles and part numbers are compatible with this kit?

The kit is specified to fit particular Honda models and engine types—always confirm fitment before buying. If you’re unsure, compare your OEM part number or use the vehicle verification section to avoid ordering incorrect components.

• Fits 2016–2021 Honda Civic 2.0L (non-turbo) and 2015–2019 Honda Fit 1.5L.

What quality checks and support come with the autoexact kit?

Each ignition coil and spark plug undergoes electrical and sealing tests during production to ensure they meet performance expectations. The kit also includes warranty coverage and customer support channels for troubleshooting or replacement needs.

• Voltage and seal integrity testing performed on every unit.
• Two-year warranty plus lifetime expert technical support.

Who is this for: This autoexact ignition coil and iridium spark plug kit is intended for vehicle owners and independent mechanics who drive compatible Honda Civic or Fit models and are experiencing misfires, rough idle, poor throttle response, or who want to proactively replace aging ignition components. It’s also suitable for DIYers seeking an OEM-fit, plug-and-play solution to avoid dealer labor, provided they verify fitment against their vehicle’s year, engine type, or OEM part number before ordering.
