Has anyone done one of these yet? I looked it up online and it didn't seem too difficult though I don't feel like fooling with it while it's cold out. I took it to the local mechanic- he told me it was an hour and a half labor so I was fine with that, now he's calling me back saying that the intake has to come off and it's three hours labor, $285! That sounds ridiculous, the dealer does it for$180 w/ parts.
