Review on Enhance Engine Efficiency with Denso 234-4077 Oxygen Sensor by Joshua Beaule

This worked great for my 1998 Dodge Dakota 3.9L V6. My truck had a check engine light on, I hooked up a code reader and it was an "upstream" O2 sensor. The truck ran terribly rich and idled very rough. Installed this Denso sensor, cleared the code and the truck is running great now. The installation went very smoothly. And it connected perfectly to my factory wiring. So for less than half the price of my local parts store and it works great, who could ask for more. Good product.
