I can't speak to the level of effort involved because I had mine done at the dealer ($1,506 to be exact). My indy wasn't available at the time so I would say it would have been anywhere from 25-30% cheaper! As others have mentioned, be sure to use the true OEM sensors from Lexus.
First time using eBay supposedly Toyota knock sensor took me 5 hours. Second time with the real knock sensors took me 2 hours. 1500 or 1200 in labor is nuts. They don't call them stealership for nothing. Should be about 300 in labor maybe 500 tops plus 300 to 500 for the two genuine knockers

Knock sensor fix? Just use OEM??
Hey guys, been having problems with my 2003 GS430. Kept getting error code P0325 for knock sensor bank one. Replaced both knock sensors today and the car ran great for about 15 minutes then CEL back on and now is throwing P0325 and P0330 for both knock sensors. I checked the wiring when I was in there and everything seemed fine. Does the 2GS have a separate knock sensor harness that can be replaced? I know other Lexus vehicles do but I couldn't see another connector to isolate the knock sensor harness.
UPDATE, READ BELOW!!!
UPDATE, READ BELOW!!!
So from all this reading I did all I have to do to fix my knock sensor code is replace with OEM sensors and tada I'll live happily ever after

my mechanic advised me to ask on here what are other routine replacements I should get parts for, that i might as well do while he is doing the knock sensor / harness replacement - other than basic hose and clamp

question for you, did performance increase for you when replacing both sensors and harness? I’m dealing with a lot of timing retardation and wondering if my knock sensors are getting old.

Yes, performance is severely cut if you receive a knock sensor code. I remember disconnecting the battery and reconnecting it and that would help for a few miles...but it would return shortly thereafter.
