There are no SAE threads on any Lexus. Not sure if its 20 or 22mm, but it definitely isn't SAE.

I'd check it myself, but don't want to disassemble things purely to check thread dimensions if someone already knows it.

Most Toyota/Lexus models with spin-on filters use SAE thread sizing, it is the same as Ford. Ditto for Denso A/C threads which are AN sizing. Stuff like oil pressure sensors are usually inch-sized BSPT as well. The oldest model I can think of that uses this style of heat exchanger for the oil is the 85 Pickup/4Runner Turbo. Older versions of the bolt would definitely have been 3/4-16UNF.
That said, for this particular bolt, it isn't listed separately so you'd have to measure it most likely. I expect it's either 3/4-16UNF or M20/M22x1.5, not sure which is more likely at this point, but if I had to guess I'd say M22.
