    You can buy a set of 4 TPMS aftermarket sensors for less than $40 and they work fine... But instead you're paying someone to do that for you via a scam and now you got all the lost time doing return hassles as well as having lost $120?

    This set of four "OEM" TPMS cost $34: Set of 4 OEM TPMS Tire Pressure Monitor Sensors For Lexus Scion Toyota | eBay

    These are standard parts across all Toyota and Lexus that are mass produced by many companies. It makes zero difference which ones you buy.

    Aftermarket Tpsm are not very reliable in terms of functionality, fals positive warnings here and there.., plus they don’t last more than 3 years top. Many will fail in about 15 months or so. My OEM sensors lasted 12 years. I don’t pay any one, extra $15 sensore swap in my local tiers center then 3 min programming via techstream in my own garage.

    The cheapo ones in the OP's photo are clearly even missing the potting compound. Doesn't seem great for longevity....

    Trust me, they all fake, made from household electronic components- not auto-grade. Some of them don’t even match sensors ID printed on sensor casing. They all all pure junk and waste of money.

    ps. Amazon refund my money but refused to post 1 star review .. lol

    Actually they have , more like extremely clear bathroom silicone or something so it’s not very visible on pictures.

    An electronic device that sends a signal if tire pressure gets low is not a performance part... Clearly, there's no such thing as a high performance TPMS. As in they're all junk wether OEM or not.

    In general, I've found that if a car part is identical for most all Lexus & Toyota that it's wise to make your purchasing decision on low price rather than OEM or quality. Of course, I could be wrong... We'd have to test lifespan of Denso OEM vs. aftermarket TPMS to be sure.

    I didn't realize denso printed boxes for them because they're made by Pacific and it looks like the Pacific logo and all the stuff is there It does look like the silicone or the potting material or whatever is not like factory or what I took out of my car which was factory wasn't as clear and legible can't see the battery that kind of thing but other than that they pretty much look the same these have QR codes on them My factory did not

    I will try to explain in plain human language. Electronic components made in various grade for different purpose and applications - meaning temperature range, durability, current consumption etc…

    Denso OEM is Toyota supplier. If you wanna go aftermarket then at least stick with we’ll know brand like Autel but you won’t save a lot of $ vs true OEM.

    Denso / Toyota OEM TPMs will outlast any well know aftermarket sensor by at least 2x-3x times.

    I think when you take them out of the package that's where the denso ends I don't think on these black parts of these TPMS sensors fakes or not denso is applied. If you look on the back of your center caps of your wheels you'll see the word Pacific these are the people that make all the tire and wheel trim for the particular model of car that you're dealing with that has the center caps with these letters on the back the TPMS sensors have the same letters and red or green in the logo depending upon what car you're working with I don't think I see dead so on the sensor at all.
