Review on 🔋 Denso 234-4800 Oxygen Sensor: Reliable Performance for Enhanced Fuel Efficiency by Cody Wuol

This is the exact brand that Toyota uses on their cars and that's why I bought it to replace the one that has over 200,000,000 miles on my Corolla. After a week or two my check engine light came on, which didn't make me very happy, but then the check engine light went out and hasn't come on for about 6 months. My gas mileage, which I was hoping to improve with this purchase, hasn't improved and I'm not even sure it could have gone down a bit. But I'm not sure because it could be my 213,000 mile fuel injectors. All in all it was easy to install and I would buy it again
