I replaced mine under suspicion of a vac leak, and it seemed very fragile.. You could very well crack it just trying to remove it. But the kicker was when i took it off, the intake side was completely clogged with black carbon. Also it seems like the EGR tube entry point at the intake is a nice spot for carb cleaner to collect, so beware if you clean your throttle body with carb cleaner, excess will run down into the tube. The braided steel replacement at Fierostore is very nice, and cheaper than a stock replacement.
