Title: Denso 234-4189 Oxygen Sensor
Review: This Sensor is used as "original equipment" in my 2003 Toyota Tacoma. If it's good enough for Toyota, its good enough for me. I have been buying parts from Autozone and Advanced Auto Parts (AAP) when I realized (Duh) I could have been buying these parts all along on Amazon. The key is finding out what part number you need. Go to your parts store and act as if you are buying. Get the partnumber and check for it on Amazon. I realized a $20 savings for this sensore. Over $80 at AAP and only $60 on amazon. I absolutely needed this part to get a check engine light to shut off so I kept $20 in my wallet. Don't know about you, but $20 is a lot of money.
Is the review positive or negative?
