I just bought the hks bov kit for my z, and i was looking to get it installed, but i don't have the tools at the place i live right now to do it myself. So i have been checking a few different places in my area but all of them are giving me super high prices(like $300) to install it, saying that the whole job will take 4 hours, and then have to remove the wheels among other things. Is this really the ussual price to install BOV's or should it be way less.
