In brief, the 2014 Honda CR-V uses iridium spark plugs. For most markets, you should use OEM-equivalent iridium plugs from NGK or Denso, with a typical gap near 0.043 inches, and plan for replacement around 100,000 miles under normal driving conditions. Always verify the exact spec for your trim and region in the owner’s manual or with a dealer.
Plug type and why iridium matters
The 2014 CR-V, powered by a 2.4-liter four-cylinder engine, relies on long-life iridium spark plugs to deliver reliable ignition over a wide range of operating conditions. Iridium plugs tend to last longer than conventional copper plugs and can help with consistent performance and fuel economy. You can source OEM-equivalent iridium plugs from major brands such as NGK or Denso that match Honda’s heat range and thread size.
Before you choose a replacement, keep these points in mind:
- Type: Iridium center-electrode plugs are standard for this engine, offering longer life and steady performance.
- Brands and equivalents: Common OEM-replacement options include NGK Iridium IX and Denso Iridium TT, which fit the CR-V’s specs.
- Gap and torque: A typical service gap is about 0.043 inches (1.1 mm); torque should follow the manufacturer's specification listed in the owner's manual or service CD for the 2.4L engine.
- Replacement interval: Under normal driving, replacement is commonly recommended around 100,000 miles, though severe service or operation in harsh conditions can shorten this interval.
In practice, selecting an iridium plug from a reputable brand that matches Honda’s heat range and thread size, and maintaining the correct gap, will ensure proper fit and longevity.
How to ensure you buy the right plugs for your car
To minimize mistakes when buying replacements, follow these steps to confirm you have the correct part for your specific CR-V:
- Identify your exact model and market (region) and check the owner’s manual or a Honda parts catalog for the recommended plug specification.
- Choose an OEM-equivalent iridium plug from NGK or Denso that matches the engine’s heat range, thread size, and reach.
- Confirm the correct electrode gap (typically around 0.043 inches / 1.1 mm) before installation.
- Ensure you use the proper installation torque and follow any anti-seize guidance as per the manual (often, no anti-seize is recommended for iridium plugs).
- Keep a record of the replacement interval and replace at or before the recommended mileage for normal driving; adjust if you operate under severe conditions.
Finally, if you’re unsure, consult a Honda dealer or a qualified technician who can verify the exact part number for your VIN and regional specification.
Summary
The 2014 Honda CR-V typically uses iridium spark plugs (OEM-equivalent NGK or Denso) with a gap around 0.043 inches, and a replacement interval near 100,000 miles under normal conditions. Verify the exact part number and gap in your manual or with a dealer, and follow the recommended torque and installation guidelines to ensure optimal performance and longevity.
