I'm getting ready to replace my bank 2 sensor 2. Any reason to go with the Lexus part vs. just getting the Bosch brand from O'Reilly's? I have a 2004 GS300 w/ 105,000. No problem getting the part from Lexus if I should, but the auto parts store is right around the corner from the house. Any thoughts are appreciated.

 

Most people recommend Amazon for the Denso/OEM at an unbeatable price, unless you gotta have them right away.

 

I recently replaced my sensor on Bank 2, Sensor 2 with a Denso. There's no splicing (which can change the wires' resistance). It's a perfect connection.

 

I have used the DENSO O2 sensors before and they are great and a lot less expensive... I reco' you go with the DENSO sensor with the connector, not the one you need to splice.

 

Thanks guys. I appreciate the advice and will do. The light has been on for a few days, so I don't think another few will really matter all that much.

 

I have the universal bosch and I did splice and solder mine but unless you have dirty flux solder I do not see why it will make a huge enough difference in resistance. I do build led boards and mess with power supply boards and the only time I have known splicing to be an issue was for a video cam that had SLIGHTLY less clarity. Also I have done about 2k miles with this sensor without issues

 

Here's a quote from the manual: "Using an ohmmeter, measure the resistance between the terminals +B and HT. Resistance: 11 - 16 ohms at 20 °C (68 °F) If the resistance is not as specified, replace the sensor."

The point is that even a small change in resistance can ruin the sensor. Your soldering skills are probably better than most due to experience. I feel more comfortable with the original part.

 

I've used Bosch universals on my previous cars and I always end up having to replace them after 2-3 years. My father's O2 sensor on his Camry was replaced 4 years ago with a Denso universal, and they're still functioning.

For the price of the Denso on amazon, I can't think of a reason why you would want to go with the Bosch unit over a proven sensor (for our cars).

 

mphsatty fair enough I do understand any change in resistance can cause error or malfunction bikes are actually really sensitive but yes I know there are benefits of the oem connecter I just didn't feel its worth the money. However, if it fails within 2-3 years I will probably go with the oem fit lol.

 

I hope it lasts a long time!
