OK so after listening with air box off and MAFs in, sound is most accute from the middle of drivers side of manifold (underneath it). What could that be? Idont think I have the time or the talent to pull the manifold right now and not have a running car.
MAF seals seemed to have some indents in them at the rear inside area, like the mafs are being pulledback and pinched. They were not symmetrical. Maf connectors had sharp bends and severe wear but seemed to not be frayed yet. See photos.
