Helpful Comparison Short Insights

When choosing the best spark plugs for Honda CRV, you need to focus less on brand loyalty and more on material and model year specificity.

For owners of the newer, turbocharged 1.5L CRV (2017+), the NGK Laser Iridium (95660 or the 4 pc NGK Laser Iridium compatible with 1.5L L4) is essential. These engines require the robust, heat-resistant, OEM-specified durability that only the Laser Iridium dual-metal configuration can provide for maximum longevity.

If you drive a mid-generation 2.4L CRV (2010-2014), you have a choice: prioritize lifespan with the NGK Laser Iridium ILZKR7B-11S or go for maximized responsiveness with the DENSO Iridium Power plugs. The DENSO option uses a finer tip for a hotter spark but might require replacement sooner.

The Bosch Double Iridium 9614 stands out as the longest-life option regardless of vehicle generation, offering dual iridium coverage and factory anti-seize plating for ultimate convenience and durability.

For earlier models, specifically the 2002-2009 2.4L CRV, the DENSO Platinum TT offers an excellent value proposition, specifically targeting improved fuel economy and quick starting via its twin-tip design. Meanwhile, the A-Premium Iridium Platinum plugs are a fantastic, budget-conscious way to achieve 100,000-mile reliability.

Final Verdict

Making the correct spark plug choice for your Honda CRV boils down to your specific engine, model year, and driving goals (longevity vs. performance).

The OEM/Longevity Champion: For virtually all late-model CRVs (especially turbo 1.5L and late 2.4L engines), the NGK Laser Iridium line is the safest and most reliable investment. They are designed to meet factory standards, guaranteeing the maximum recommended service interval.

The Performance Pick: If you are chasing a noticeable bump in throttle response and immediate power, the DENSO Iridium Power (for 2.4L engines) or the NGK Iridium IX are the way to go. They use ultra-fine tips to deliver the most intense spark possible.

Best Budget/Value Alternative: If you have an older CRV (pre-2010) and need robust 100,000-mile plugs without the premium price tag, the A-Premium Iridium Platinum options offer reliable, double noble-metal construction that meets or exceeds OEM quality for their intended fitments.

Best Spark Plugs For Honda CRV FAQ

Q1: How often should I replace the spark plugs in my Honda CRV?

A: The replacement interval largely depends on the type of spark plug you choose. Standard copper plugs need changing around every 30,000 miles, but most modern CRVs use Iridium or Platinum spark plugs. These plugs, like the NGK Laser Iridium, are engineered for extended service intervals, typically lasting between 80,000 and 100,000 miles. Always check your specific CRV owner’s manual or the manufacturer’s recommendations for the most accurate timeline.

Q2: What are the common signs that my CRV spark plugs need to be replaced?

A: Failing spark plugs can cause several noticeable issues. Look out for rough idling (the engine shaking unevenly), difficulty starting, a noticeable drop in fuel economy, poor acceleration, and engine misfires (often accompanied by the Check Engine Light flashing or staying on). Replacing them promptly restores engine efficiency.

Q3: Is there a difference between Iridium IX and Laser Iridium NGK plugs for the Honda CRV?

A: Yes, there’s a key difference related to longevity. Iridium IX plugs are designed for maximum performance, using a fine tip for a powerful spark but generally have a slightly shorter lifespan. Laser Iridium plugs are NGK’s highest durability line, featuring iridium on the center electrode and platinum on the ground electrode, making them the standard choice for 100,000-mile OEM applications in the Honda CRV.

Q4: Do I need to gap new spark plugs before installing them in my CRV?

A: Generally, no. Most modern, high-quality spark plugs—especially Iridium and Platinum plugs like the Bosch or NGK Laser series—are factory pre-gapped to the exact specifications required by your Honda CRV engine. Attempting to adjust the gap on fine-wire iridium tips can easily damage the delicate electrode. Only older, copper plugs sometimes require gapping. Always confirm the required gap in your owner’s manual.

Q5: Can using the wrong spark plug type damage my Honda CRV engine?

A: Potentially, yes. If you use a plug with the wrong heat range or thread reach, you can cause serious issues. Using a plug that runs too hot can lead to pre-ignition and engine damage (especially critical in the 1.5L turbocharged CRV models), while a plug that is too long can physically hit the piston. Always match the spark plug reference number precisely to your specific CRV engine year and size.

Q6: Should I choose Platinum TT or Iridium plugs for my older CRV (2.4L)?

A: Both are excellent upgrades over standard plugs. DENSO Platinum TT plugs are specifically engineered to optimize the spark for fuel economy and reliable starting by reducing electrical quenching. Iridium plugs (like NGK Iridium IX or DENSO Iridium Power) focus slightly more on maximum ignition power and responsiveness. If longevity and efficiency are your priority for high-mileage use, the robust dual-metal options are usually preferred.
