Review on Denso 234-4260 Oxygen Sensor: Ensuring Optimal Engine Performance by Michael Gupta

I needed a sensor for my Toyota '09 and bought it from my local auto parts store. I paid a hundred dollars and after installing the part found that it didn't work, the check engine light was still on. I took the part back hoping for a refund but this didn't happen, there were no exchanges for electrical parts. The dealer wanted over $150 for a genuine Toyota part. I found a Denso sensor on Revain for less than $60 and decided to order it. Item arrived and fits my Toyota like a glove, the engine light is no longer on. Highly recommended Denso sensor, great price, fast shipping!
