Review on 🚀 DNA Motoring OEM-ITM-001 Upper Intake Manifold 615-175 for 1999-2004 Ford Mustang 4.6L V8 SOHC by Doug Darling

Not installed yet but I have to say I'm concerned this thing might damage my engine. Terrible inside! Full of potentially loose plastic waste that could potentially break and end up in my incinerator. I don't know what else to say. Manufacturers should have a deburring station... or something like that. In the last photo, the original intake manifold for comparison, note the smooth edges. With this product, the turbulence of the air entering the engine will be much worse.
