2016 Toyota Camry SE, engine 2AR-FE, 103k miles

Sometimes, while driving, I'll start hearing a noise that's kind of like a squeak, but pulses at around 8hz. Pulled over, listened around, sounds like it's coming from somewhere near where the engine air flows after the filter box. Any ideas what could squeak around there, and maybe how I could verify it?
