A-Premium Iridium Platinum Spark Plugs Pack of 4 for Honda CR-V/Civic — 12mm Thread, Long-Life 80K–100K mi

A-Premium Iridium Platinum spark plugs (pack of 4) are high-performance replacement plugs engineered with an iridium tip and platinum core to deliver reliable ignition and extended service life for compatible Honda, Hyundai, Kia and Acura engines.

These A-Premium plugs combine an iridium center electrode with a platinum core and a 0.044-inch factory gap to match OEM-style ignition characteristics. Built with a 5/8-inch hex, 12 mm thread diameter and 26.5 mm reach, the plugs are designed to fit specified L4 1.6L–2.4L engines across multiple makes and model years. The electrical resistance is specified at 5000 ohms, and A-Premium recommends replacement intervals aligned with long-life iridium/platinum service—typically in the 80,000–100,000 mile range for sustained performance.

Will these spark plugs fit my Honda CR-V or Civic?

Check engine type and model year against the listed fitment. The pack is compatible with many Honda 2.4L four-cylinder applications, including CR-V and Crosstour 2012–2015, Civic 2012–2015 (1.8L and 2.4L), and Accord 2008–2012 where that spark plug specification is required.

• Compatible with Honda CR-V/Crosstour 2012–2015 L4 2.4L
• Fits Civic 2012–2015 L4 1.8L and L4 2.4L engines
• Check your owner’s manual or current plug part numbers (see reference numbers provided)

How do these A-Premium plugs differ from standard copper plugs?

Iridium and platinum materials have higher melting points and allow for finer electrode tips, improving spark precision and durability versus common copper plugs. That typically leads to longer service life and more consistent ignition over time, especially in modern engines that demand tighter tolerances.

• Iridium center electrode tip for a fine, durable spark point
• Platinum core for improved wear resistance compared to copper
• Long-life design—recommended replacement at 80,000–100,000 miles

What technical specs should I confirm before buying?

Confirm thread diameter, reach, hex size and gap match your engine’s requirements to avoid installation issues. This A-Premium set provides the common 12 mm thread, 26.5 mm reach, 5/8-inch hex and a pre-set 0.044-inch gap—measure against OEM specs or the old plug before installation.

• Thread diameter: 12 mm
• Reach: 26.5 mm; Insulator height: 51 mm
• Gap: 0.044 in; Resistance: 5000 ohms; Hex size: 5/8 in

How should I install and maintain these spark plugs for best results?

Install using a torque wrench and the correct socket to prevent cross-threading or over-torquing. Replace in sets where applicable, follow the vehicle manufacturer’s torque and gap-check procedures, and inspect ignition coils and wires during service for a complete tune-up.

• Tighten to manufacturer torque spec; avoid overtightening
• Verify gap before installation and use anti-seize only if recommended
• Replace plugs as a set and inspect ignition components concurrently

Who is this for: Drivers and DIY mechanics who need an OEM-style long-life replacement for four-cylinder Honda, Hyundai, Kia or Acura engines seeking improved durability over copper plugs. This 4-pack from A-Premium suits owners performing routine maintenance, tune-ups, or restorations on compatible L4 1.6L–2.4L engines who require correct thread size, reach and a factory-style gap with iridium/platinum construction.
