Long story short, I replaced all my spark plugs, spark plug tube seals, ignition coils (2, 3, 5, 8) about 13k miles ago. Today, the CEL goes off again and those codes pop up. No loss in power or any changes. Any idea on what it could be? I've checked all the wiring and everything looks good. No oil in the spark plug chambers (was the culprit before).

What brand of spark plugs and ignition coils did you use to replace the original ones and where did you buy them? My first thought was that you might have sourced some spark plugs/ignition coils from a wrong supplier. Since your car have been running fine for 13K miles, I'd just clear the error code and see what happens. If you have Techstream, use it to clear the error codes. If you don't have Techstream, unplug the negative terminal on your battery and wait for 30 minutes to reconnect (this will clear the current error code but not historical error codes). If the error code go away, enjoy driving. If the error codes come back right after you re-start the engine after clearing the codes, I'd replace the spark plugs and ignition coils with genuine Toyota parts purchased directly from a Toyota or Lexus dealer.

More than likely the coils and plugs are not Denso that you received often I have seen stuff listed on RA as OEM components to have something else show up. I would recommend just buying OEM replacements from Lexus there not that terrible.

Rock Auto is a reputable vendor. Nonetheless, I'd pull out a spark plug to have a visual inspection and examine the condition of the spark plugs. For some reasons, with 2007-2010 LS460 cars, Number 8 spark plug tends to wear out sooner than others. I'd just pull out Number 8 spark plug as the first one to examine and take a look at its condition. If it carries signs of wearing out (i.e., deposit, erosion, web surface, etc.), I'd replace it and see if the error codes go away. Because spark plugs are mission critical to engine performance, I usually buy them directly from a local Toyota dealer with the required Lexus part number. Usually, Toyota dealers sell the same Lexus spark plugs with 10%-15% lower price.
