I haven't done it personally. All it does is eliminate the intake sounds that get pumped into the cabin. The tube is there because modern sound dampening has removed a lot of the non-exhaust tones that used to be present, especially in old muscle cars. Think of it as a drum your engine beats to let you know it is still alive. If you don't like the sound, removing it has the benefit of getting rid of it. I'm not even sure my ears work well enough to distinguish it anyway. Also, no stupid questions, only inquisitive idiots
One of the first things I did when I got my '18 GT Premium. Main reason for removing it was it looks ugly as sin under
the hood; like something from a Dr, Seuss book! Whether it reduced engine sound in the cabin, who knows. Just
removing it makes you think the sound has changed. Totally unnecessary piece of junk IMO.
Cleaning up the engine compartment hasn't been a big motivator in my relationship with the car. I viewed the sound tube as a waste of energy and materials, and the introduction of a phony aspect to the vehicle. Kind of like brake scoops behind the doors. Now, if they had put those on with the money wasted on the tube, I might have left them on; could the scoops be made functional? I'd guess so. No such value in the tube.
I put a plug in mine. I don't think it made a perceptible difference in what I hear in the cabin. Not only was it a goofy solution to a problem that probably didn't exist, it didn't work. I hope Mr Ford learned from this.
Removing or plugging the sound tube on a car with the factory CAI and exhaust doesn't make much of a difference in reducing the sound in the cabin. It makes more of a sound difference if you have an aftermarket CAI, exhaust, Big Mouth Air Intakes, etc....
Removal does declutter the engine bay but doesn't help with the cleaning part.
What you want to hear in the cabin is a personal choice. Leave it on, pull it off, or stick a valve in it.
