need help with oxygen sensors
 

Hi all--

I own a 1999 GS-300. My mechanic tells me that the check engine light is on because the front and center oxygen sensors are bad. I want to buy them online but there are several brands with different part numbers (Bosch, Denso, NTK, etc) and no cross-reference info on the OE part number. Any help will be greatly appreciated.

Thanks

Lexus recommend Bosch parts
