Pretty sure Denso is the OEM MAF, given that this is a Toyota.
Cleaning MAFs is pointless for the 2 microscopic specs of dust they may accumulate.
If you are buying MAFs from eBay/Amazon, odds are you're not buying real ones.
What says the MAF has died repeatedly? What is the CEL you are getting?
Bought the MAF from Advance Auto. Denso #197-6110. Code is P0101. No other codes and obd shows airflow and fuel trims going haywire, like 25 grams per second at 1500 rpm, and negative 20+ LTFT. I also read reviews that this MAF didn't last long for other people either.
I think you're right, though. Most "AC Delco" parts for this car are really Denso or Toyota.
I also don't think I was clear before. I've only bought this one MAF that failed in 5 months. The original one failed after 12 years.
