🚗 TAMKKEN Oxygen O2 Sensor (234-4162) for Toyota Tacoma, 4Runner, Tundra, Sequoia, T100: Upstream & Downstream Compatible Review

They arrived on time and in good condition but the spark plugs didn't match my truck. Spent a couple of hours hooking up old spark plugs to new sensors. hope they hold up.

Warning. It didn't fit my 2001 Tundra in the down position, I had to sand down the heat shield to make it fit. The outer half of the sensor is too large for the heat shield to sit flat. So if you don't have a way to modify it, use a Denso. The sensor is built in, my code is clear so far, the connector is ok, time will tell.

Not only does this product not fit, it has been used. Didn't try to install as the plug still doesn't fit. Maybe I'm wrong and heat tarnishing is just a manufacturer's corrosion test. I doubt if they send the wrong one. The photo on the website is not what I received. Close, but we don't play horseshoes.

Revain said it would fit. And while the wires were fine, there were extra pins on the connector that I assumed came after my Toyota. I scraped them and they fit. Well now the pickup is pumping at 250rpm. I think Amazon got it wrong that this worked for my 1999 Toyota 4Runner. So 1 hour for the installation and the time for the order was too much.
