Review on 🚀 High-Performance Denso 234-4153 Oxygen Sensor for Efficient Engine Performance by Mark Cannon

Worked great on my 1999 Toyota 4Runner 3rd Gen 3.4L v6 4x4 Automatic. OEM DENSO is the ONLY one recommended for these trucks as I've heard other brands of sensors can cause problems. Always use OEM for each sensor. They also came with a gasket that runs between this and your exhaust pipes. I installed new sensors for a fraction of what the dealer would charge and my truck is running perfectly again! Very happy! It should be noted that this is the bottom sensor.
