OEM, but do not buy from Amazon. Buy from NAPA, O'Reilly, dealer, whatever. You only change them once every bazillion years.

FK20HRR11 is what my manual says to use but I can't find them in the usual places. IKBH20TT is all that's available. I wonder whether that's what the dealer uses as it's what Denso now recommend. Looks like the correct option.
