[ROUSHAC]

I remember hearing a quote a LONG time ago (I think it was from Semon "Bunky" Knudsen) that said: "Functional mechanical parts are in a car for a reason. Parts that aren't needed cost nothing for the car maker to buy, install, or warranty. If it's in there, you need it, because if you didn't need it, the car makers wouldn't put it in your vehicle in the first place."
