🔧 Enhanced Efficiency Denso 234-4045 Oxygen Sensor Review

I live in a state and county that expects humans to create emissions. It's been a few years now and it works fine. They are inexpensive and have lasted thousands of miles and years!

You need a special air/fuel ratio sensor! They are made by Denso and NTK! Oxygen Sensor Denso 234-4373 (Air Fuel Ratio Sensor).

Fits perfect, works great. These O2 sensors are the BEST Ford Modular v8 preheated O2 sensors on the market and they don't cost a fortune either! highly recommended!

Excellent price! A brand new undamaged O2 sensor, arrived in great packaging, arrived very quickly and works great! Thanks it's nice to have honest sellers (unlike eBay which isn't honest anymore)

Purchased (4) O2 sensors. An upstream connector was so bad it wouldn't snap into place. All sensors DO NOT have side rails like the OEM. What prevents you from installing the wrong sensor in the wrong place. I thought Denso was about quality, nothing more. 1 out of 4 was bad. I had to cut, solder and heat four wires to the old terminal.
