I’m ordering the parts from Lexus. Going all OEM because I know how picky Toyotas are. Learned my lesson with aftermarket tire sensors lasting only a couple months.
Parts is about $750 from what I gathered. The rest is labor from the ASE Toyota tech. The guy who quoted $900 is a shop closed by for convenience only. Might go with the Toyota tech even though he’s more on the pricy side for a piece of mind. Saving the back coil packs for future use in case the front goes out.

Not sure about the RX350 but on my car I bought the knock sensor harness too and I went with OEM.
Not very expensive at all.
Reason why is the short harness wire can go bad too and throw a knock sensor code.
What I'm trying to say is you could have a bad knock sensor or a bad knock sensor cable.
Disclaimer, this is on a RX330, no idea about the newer engine in the RX350.
Imaging how bad that would suck to do all that work and find out it was a bad cable. Haha 🤓
