Review on Denso 234 4189 Oxygen Sensor by Kenny Sanchez

This sensor is used as "Original Equipment" in my 2003 Toyota Tacoma. If it's good enough for Toyota, it's good enough for me. I bought parts from Autozone and Advanced Auto Parts (AAP) when I realized I could always buy those parts from Revain. The main thing is to find out what part number you need. Go to your parts store and pretend to buy. Get a part number and check it out at Revain. I realized I saved $20 on this sensor. Over $80 at AAP and only $60 at Amazon. I desperately needed this part to turn off the check engine light, so I left $20 in my wallet. I don't know about you, but $20 is a lot of money.
