Mine's gone. I won't question the reasons why you want it, but the car itself is better off without it. All it does is trap heat and prematurely age your engine.
If you have a Zetec, the sound-proofing it offers isn't great and isn't really needed.
If you have a V6, take the pad out, turn down your stereo, and listen to the 6-cylinder music.
There really is no benefit to having it.
