SK20R11 Denso Iridium Long Life - about 7-8 bucks each. There may be less expensive sources but watch out for cheap fakes so check the box and plug carefully no matter where you source them. I purchased the ones below and had no issues.

SK20R11 Denso Iridium Long Life is what I just used (122k miles).
BTW: Lexus spark plug interval is 120k so not really necessary at 94k unless you want to be proactive which is understandable as well.
Second, if your DIY then be careful when pulling the spark plug wire clips out. They are hard to push in on the release and then pulling up on them without pulling on the wires, which are pretty thin. With the age and they way you have to grab them you can easily pull or rip out a wire from the clip....ask me how I know. The first LS plug change I did I had no issues, the last one I did last week I pulled the wire on one and had to replace the clip. Which if you do accidentally there are threads on here with the part numbers and what to do.

I also highly recommend this. It's worth the $14 and with all the money you'll save DIY it's no brainier.

Its super easy very good task to start out with as you learn to fix your own car. Only thing to be carefull of is dont overtighten the plugs and break them in the motor, and dont drop anything down the hole when you have the plugs removed.
