The 2012 Honda CR-V uses iridium-tipped spark plugs for its 2.4-liter engine. Replace with iridium or OEM-equivalent plugs from reputable brands (such as NGK or Denso) that match Honda’s heat-range and set the gap to about 0.043 inches. The exact part number can vary by market and trim level.
In depth: In North America, the 2012 CR-V is equipped with a 2.4L inline-4 (K24Z3) and uses long-life, iridium-tipped plugs designed for extended maintenance intervals. Because spark plug part numbers can differ by region and supplier, it’s best to confirm the exact OEM part for your VIN and model year with Honda Parts or your local dealer. The ignition system on the CR-V uses a coil-on-plug design, which also influences installation torque and gap accuracy.
Spark plug type used in the 2012 CR-V
Most 2012 CR-V models destined for the North American market use iridium-tipped spark plugs as original equipment. Iridium plugs offer long life and reliable ignition in a compact, coil-on-plug setup. Some markets or vehicle configurations may utilize platinum or other variants, but iridium is the prevailing OE choice for the 2.4L engine in this year.
What this means for replacement choices
Because spark plug availability can vary by region, you may encounter NGK or Denso iridium plugs that meet the same specifications as the OEM part. The critical factors to match are the heat range and the gap, not the brand alone. Aim for an iridium plug that fits the K24 engine with the correct heat rating and a gap near 0.043 inches.
If you cannot locate the exact OE part number, use an aftermarket iridium plug from a reputable brand that lists compatibility for the 2.4L CR-V (K24Z3) and verify the recommended gap before installation.
Replacement options
Before listing options, note that you should select plugs that match the OEM heat range and gap. Here are common choices that fit the 2012 CR-V's 2.4L engine:
- NGK Iridium IX or Laser Iridium plugs designed for the 2.4L K-series with the correct heat range
- Denso Iridium Power plugs designed for the 2.4L K-series with the correct heat range
- OEM-equivalent platinum plugs from NGK or Denso if iridium is unavailable, ensuring the same heat range and gap
Concluding: When replacing, verify the exact part number for your vehicle with a parts catalog or dealer, and ensure the correct gap and torque as specified in the service manual.
How to identify the exact spark plug you need
To ensure compatibility, confirm these details before purchasing:
- Engine code: 2.4L I-4 (K24Z3) for the North American 2012 CR-V
- VIN or model trim can affect the exact plug family and part number
- Gap: typically 0.043 inches (1.1 mm) for this engine
- Brand preference is acceptable as long as the plug meets OEM specs and longevity
Concluding: The best practice is to refer to the owner's manual or Honda Parts Catalog for the exact OE part number for your VIN, and follow the recommended replacement interval.
Summary
The 2012 Honda CR-V’s 2.4L engine normally uses iridium-tipped spark plugs. Replacement plugs should be iridium or OEM-equivalent with the correct heat range and a 0.043-inch gap. Always verify the exact part number for your vehicle’s VIN and market with Honda’s official catalogs or a trusted parts supplier to ensure proper fitment and performance.
