Review on 🔧 Enhanced Denso 234-4138 Oxygen Sensor for Optimal Performance by Brian Nelson

I put 1 to be noticed. Great product but poor part number identification. The Revain and Denso websites say this part fits my 2004 4Runner, but that's not true. I called the Toyota dealership and had to look up Toyota OEM parts by VIN as there are several listed for that year, make, model and engine. To make matters worse, the Toyota part number doesn't overlap with the Denso part number, so I ordered the part from the dealer for almost $200. See photo for comparison. Wires of different lengths and plugs of different designs.
