Default Spark plug recommendation. 2021 Lexus IS350

I am almost due to change my spark plugs for my 2021 lexus IS350. I am considering purchasing spark plugs thru rockauto.
Which one would be better between the spark plugs they have on site. Both are denso.

https://www.rockauto.com/en/moreinfo...hoice=0-0-0-1: part number: FK20HBR8 ( I believe this is the OEM spark plug) Pre-Set Gap: 0.032
https://www.rockauto.com/en/moreinfo...=7212&jsn=1038 part number: IKBH20TT (the one I might consider) Pre set gap: 0.040

I've noticed the difference between the pre set gap. Would that make any performance difference and or any issue down the line?

Thank you!
