A-Premium Iridium Platinum Spark Plugs for Honda/Acura 2.4L L4 — Pack of 4, Fine-Wire, Pre-Gapped

A-Premium Iridium Platinum Spark Plugs are a four-pack of fine-wire, iridium-tipped plugs engineered to deliver reliable ignition performance and long service life for 2.4L L4 Honda and Acura engines.

These spark plugs pair an iridium center-tip with a platinum core to improve ignitability while resisting wear. Designed to match OEM specifications for Honda and Acura 2.4L inline-4 models, this pack includes four plugs with a 0.044 inch gap, 12 mm thread diameter, and a 26.5 mm reach. The construction focuses on consistent spark energy and extended replacement intervals, making them suitable for routine maintenance or performance-oriented tune-ups.

Which vehicles will these plugs fit?

These A-Premium plugs are tailored for specific Honda and Acura 2.4L L4 applications. They are compatible across multiple model years and trims where the OEM reference numbers match.

• Honda CR-V: 2010–2014 L4 2.4L
• Honda Accord: 2008–2012 L4 2.4L (non-PZEV Federal emissions)
• Honda Crosstour: 2012–2015 L4 2.4L
• Honda Civic: 2012–2015 L4 2.4L
• Acura ILX: 2013–2015 L4 2.4L; Acura TSX: 2009–2014 L4 2.4L

How do these plugs improve starting and throttle response?

The iridium tip and fine-wire design concentrate the spark and lower voltage loss at the electrode, improving initial ignitability. That translates to quicker starts, steadier idle, and more consistent throttle transitions under load.

• Iridium center electrode for a stronger, focused spark
• Fine-wire tip reduces voltage required for ignition
• 5000 ohm resistance for stable suppression of electrical noise
• OEM-aligned dimensions ensure proper seating and combustion

What are the technical specs I should know before buying?

Check key dimensions and electrical ratings against your vehicle’s service manual to ensure fitment. These plugs mirror common OEM reference numbers and provide clear measurements for safe installation.

• Gap size: 0.044 inch (pre-gapped)
• Center electrode tip: iridium; core material: platinum
• Thread diameter: 12 mm; reach: 26.5 mm; hex size: 5/8 inch
• Insulator height: 50 mm; resistance: 5000 ohms

How long will these spark plugs last and when should I replace them?

Iridium and platinum alloys resist electrode erosion much longer than standard copper plugs. For routine driving conditions, these plugs are designed to remain effective for high-mileage intervals, but inspection is still recommended during scheduled maintenance.

• Recommended replacement interval: roughly 80,000–100,000 miles under normal conditions
• Inspect earlier if you notice rough idle, misfires, or increased fuel use
• Follow manufacturer torque specs and ignition coil handling precautions during installation

Who is this for: A-Premium Iridium Platinum spark plugs are best for owners of Honda and Acura vehicles with 2.4L L4 engines who want an OEM-like replacement that balances improved ignitability with long service life. They suit DIY mechanics and professional technicians seeking pre-gapped, specification-matched plugs for routine maintenance or performance-conscious tune-ups. If you need plugs matched to the listed model years and reference numbers, this four-pack provides a cost-effective, high-durability option.
