Review on 🔌 Denso 234-4233 O2 Sensor by Antonio Liu

I can't believe how great this product is. The exact same part at my local dealership was almost double the price. If you order from a mechanic, the price is almost triple. It only took fifteen minutes to change this part, turn off my check engine light and take my car back from 16mpg to 34mpg. Make sure you have an O2 socket as regular sockets will not work. I was able to use a temporary outlet from my local lot and had the part replaced at their lot. If your old sensor has frozen/stuck, you can take the part to a mechanic and pay to have it replaced (between $30 and $60). Either way, look at it, it's a worthwhile purchase.
