I was excited to try the Denso 3439 spark plugs, but one of them stopped working after a month. I thought they were high quality, but the performance didn't last. I'm not sure if it was just a bad batch or what, but I'm feeling let down.

Great plugs, but shipping took a while
These Denso spark plugs are excellent for my Toyota Camry. They fit perfectly and the car feels more powerful on acceleration. However, I was a bit disappointed with the delivery time; it took about a week longer than expected. Still, I’d buy these again regardless.

Solid performance in my old car
I've been using these Denso 3439 spark plugs in my 2005 Honda Accord for a couple of months now, and they really improved the engine's responsiveness. The installation was straightforward, and I appreciate the quality of the build. Definitely worth the investment if you want to keep your vehicle running smoothly!
