I’ve been using this spark plug for a while now, and I’m really impressed with its performance. The iridium tip has definitely improved the ignitability of my engine, and I’ve noticed better fuel economy too. My only minor complaint is that it’s a bit pricey, but considering how well it performs, I think it’s worth the investment.

What’s the secret to making this spark plug so effective? Is it the trivalent metal plating or the iridium tip that makes all the difference? I’d love to know more about the technology behind it. Can someone please explain it to me?

Hi Hannah Lee, Thank you for sharing your thoughts about our NGK Spark Plug Iridium IX CR9EIX (3521)! We’re thrilled to hear that it’s been effective for you. The secret to its success lies in the combination of both the trivalent metal plating and iridium tip. The trivalent metal plating provides superior anti-corrosion and anti-seizing properties, which helps prevent fouling and ensures a consistent spark. Meanwhile, the iridium tip allows for improved ignitability and more complete combustion, resulting in cleaner burning and reduced fuel consumption. This synergy enables the spark plug to deliver a powerful and reliable performance. We’re glad you’ve experienced the benefits of this technology! If you have any further questions or concerns, please don’t hesitate to reach out.

I’ve tried other spark plugs before, but this one is definitely the best. The corrugated ribs prevent flashover, which has given me peace of mind while riding. I’m also loving the smoother acceleration and better fuel economy. My only question is: does it work equally well on smaller engines or is it specifically designed for high-performance motorcycles?
