That's why I went AEM dry filter for my stillen gen3. Indie labs also show better filtering so why deal with the hastle of outdated oiled filters for nothing.

Yeah but I actually got rid of my filters before replacing both MAF sensors, so that shouldn't be the problem anymore. It may be a wiring issue, but is that something you can see from an inspection? Because the 2-3 times I brought the car in to Nissan for an inspection/service, they couldn't find any problems.

No. You (or the dealer) should be able to read the MAF signals via OBD/CAN to check for wiring problems.

I suggest opening all the connectors between the MAFs and ECM (see FSM for harness layout) and cleaning everything with contact cleaner.
