Loud sucking noise coming from engine 4.6 triton 04 f-150
When approaching 3000 rpms I hear a loud sucking noise coming from the engine. No check engine lights and no performance issues, just a very loud and obnoxious noise. HELP

Have you checked the intake tube for cracks/tears?

Also check for leaves in the air box before the air filter.

Also check the filter canister clamp. They like to rust out and come apart. It's a ~$15 item.
