Review on 🔍 Denso 2344261 O2 Sensor by Emmanuel Pictorial

Fits perfectly on my 2001 Toyota 4Runner SR5 with 190,000 miles. I replaced the front A/F sensor about 6 months ago because the check engine light was on. The CEL tripped and then came back with a P0420 code so instead of replacing the cats I replaced that O2 sensor. There is no light yet. I sprayed a PB blaster a few days before attempting to remove the old one, and it came out pretty easily. I was able to use a 22mm open end wrench. I had enough room to turn the wrench to break it. If you are a DIY lover, you can change it by yourself.
