A-Premium Iridium Platinum Spark Plugs Pack of 4 for 2.4L L4 Honda/Acura — Fine-Wire, Pre-Gapped 0.044 in

A-Premium Iridium Platinum Spark Plugs (pack of 4) are precision-engineered fine-wire electrodes designed to deliver dependable ignition and long service life for 2.4L L4 Honda and Acura engines.

These spark plugs combine an iridium-tipped center electrode with a platinum core to balance reliable starting, steady combustion, and extended replacement intervals. Built to meet common OEM fitments and tolerances, this four-pack fits many 2.4L four-cylinder applications — including select Civic, Accord, CR-V, Crosstour, ILX, and TSX models — and comes pre-gapped to 0.044 in for straightforward installation.

How do these spark plugs affect engine starting and throttle response?

Iridium on the center electrode offers a very fine, durable tip that concentrates the spark for easier ignition of the fuel-air mix. The precise gap and low-resistance design help create a consistent arc, which supports crisp throttle response and smoother idling.

• Fine-wire iridium tip for concentrated spark energy
• 5000 ohm resistor to reduce radio-frequency interference
• Pre-set 0.044 in gap for reliable starts out of the box
• Optimized reach and hex size to match OEM plug wells

Are these plugs the right fit for my vehicle?

The pack is specified for many Honda and Acura 2.4L L4 engines; confirm with your owner’s manual or parts diagram to be certain. Reference numbers and cross-compatibilities are included to help match factory part numbers and aftermarket equivalents.

• Compatible with Honda Accord (2008–2012 L4 2.4L non-PZEV)
• Fits Honda CR-V (2010–2014 L4 2.4L) and Civic (2012–2015 2.4L)
• Also fits Acura ILX (2013–2015) and TSX (2009–2014) 2.4L engines
• Cross-reference: ILZKR7B-11S, 12290R40A01 and similar numbers

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

Iridium and platinum materials are chosen for wear resistance, so these plugs are engineered for extended intervals compared with conventional copper plugs. Typical recommended replacement ranges for platinum/iridium types fall between 80,000 and 100,000 miles under normal driving conditions, though driving habits and engine tune can change that timeline.

• Durable iridium tip and platinum core for slow electrode wear
• Designed for up to 80,000–100,000 miles in many use cases
• Inspect sooner with frequent short trips or high-load driving
• Replace in matched sets to maintain even cylinder performance

What are the technical specifications and installation details?

The plug dimensions and electrical properties match common OEM requirements so they seat cleanly and torque to spec without modification. Use a torque wrench and anti-seize only if recommended by the vehicle maker; the plug comes with a standard 12 mm thread diameter and a 5/8 inch hex for easy wrenching.

• Center electrode: iridium tip, platinum core for strength
• Resistance: 5000 ohms; Gap: 0.044 in; Reach: 26.5 mm
• Insulator height: 50 mm; Thread diameter: 12 mm; Hex: 5/8 in
• Sold as a pack of 4, ready-gapped for many 2.4L engines

Who is this for? Drivers and DIY mechanics who own compatible Honda or Acura vehicles with the 2.4L four-cylinder engine and want a long-lasting, OEM-minded replacement plug will appreciate this pack. It's suitable for routine maintenance, tune-ups, or preventive service where balanced ignitability, interference suppression, and extended wear life are priorities. Always double-check vehicle fitment and torque specifications before installation.
