Whatever Lexus recommends from the factory. Check your owner's manual.

Use Lexus plugs (Denso), part number is 90919-01249. The Denso part number is FK20HBR11. Be wary of where you buy them, many of the ones that are significantly cheaper (e.g. $40-50 for a set of 6 vs $70-90ish) are fakes. Check who is selling them, if it's not shipped/sold by Amazon, or from some Lexus dealer selling on eBay/Amazon, don't buy them.

The OE plugs from my local Lexus dealership were ~$28/plug Canadian, plus tax. Really not that bad compared to my mom's Nissan Versa that has $45 spark plugs somehow.
