I replaced mine with an OEM Denso one from RockAuto and used a 5% coupon. It’s not an expensive sensor.

UPDATE!!
I have been driving mine for about 3 days now and still no code so far so good I don’t know if cleaning the maf was the fix or fixing the leak on the AOS. I also have the 44k on the way I’ll be throwing that in there too.
