Solid Performance and Easy Install
I replaced my old oxygen sensor with the Denso 234-4400 and noticed improved engine performance almost immediately. The installation was straightforward, and it fit perfectly in my 2005 Honda Accord. Definitely worth the investment for anyone looking to boost their car's efficiency!

Good Sensor but Shipping Delay
The Denso downstream oxygen sensor works fine, but I had a bit of trouble with shipping; it took a week longer than expected to arrive. Once it got here, installation was a breeze and my car is running smoother now. Just wish it hadn’t taken so long!

Stopped Working After a Month
I was really hopeful about the Denso 234-4400, but unfortunately, it stopped working just a month after installation. The car started throwing codes again, so I had to go back to the shop. Disappointed, as I expected better quality from Denso.
