Product ReviewsOxygen Sensor-Natural DENSO 234-4209

If you can cut wires and put them securely together, you can save money

I'm very pleased with this purchase and save a lot of money. I saw several comments from people complaining about the missing connector. The description states that there is not connector, if you don't want/feel you want to do this type of work don't buy. I bought it 'cause I can do it and it was not a major issue securing the wires to the old oxygen sensor connector. Read full review...

Denso sensors work great!

If you are confident with wire splicing these are a bargain. Make sure you leave enough heat protective wrap from the old connector to be overlapped with the new wrap. Staggering the splices is it necessary if you want to fit them inside the wrap. You could put the spices all together if you are not sure how to stagger them and keep the lengths even. I siliconed the ends of the spices for corrosion protection. It's a bit of work but it saved substantial money doing all four O2 sensors.Read full review...

Not a oem like I ordered

This product works like it should . But I was disappointed because I order oem and got a universal instead and had to make it fit which took more time.
Did not have time to send it back. Rick

This sensor does not work well in the upstream location on a 2002 Toyota Camry 2.4l

I had no problem splicing the wires; however, my engine did not respond well to this O2 sensor. It did not work for my 2002 toyota camry 2.4l.

Dont waste your time

I would not recommend buying this part it doesn't NOT have connection. They want you to use heat shrink to connect that's is not the correct way.

Way to Go

I used these to replace the 4 sensors in my Lexus LS430. What a horrible job to do but as it saved me $1000 I can wear that. The product itself is excellent.

GREAT sensors ! Great price ! 2006 Toyota Sienna XLE

Easy to install but don't forget you need to splice the wire to connect the plug from your old one. Check youtube videos on how to.
