Mine is an 06. But are you talking about the O2 sensors or the TPM sensors? I am talking about the O2 sensors

 

Oh my bad. I assum the TPMS.

I looking over all the literature I can find, Looks like the only difference is the length of the wire which is easily corrected by splicing to the old sensor wire and thread size and depth of probe and connector. The sensors are all the same internaly. Match those and you should be good to go. The prices run the gammut from $15 to over $200. I dont think you gain anything by going by the price. Get one and splice it in (splicing eliminates the need for a special socket!!!) and might as well go cheap. I have done these before and it always seems to work even though the sellers try to scare you into spending more money. I would stick to Denso though as that is OEM for Lexus.
