I am taking my '08 Coupe in to have a few things completed and wanted to get an idea of the charges after speaking briefly with the dealer. If possible, let me know your guesses:
1. Swap out intake manifold with Arrow ported intake (both OEM).
2. Change rear differential fluid.
3. Bleed brake system with Castrol SRF that I supply.
Thanks!
If you have the Arrow ported intake, you should be able to swap that out in a couple hours at most. And, that's doing it yourself and learning along the way. A dealer should be able to do it quicker since they know the little tricks. The intake on Gen IV cars is really easy to remove and replace.
The diff fluid is very easy and you'd be best off doing it yourself... I personally like Redline 70w140 diff fluid with additive to refill. The hardest part of that one is just putting jack stands under your car - and that is EASY.
For the brakes, go out and get yourself a set of speed bleeders and do that yourself, too. That whole job shouldn't take more than an hour or so.
As you can see, I'm an advocate of doing the simple stuff myself - I'm sure someone will chime in with possible dealer costs. You can use the above as a sanity check in case someone comes in with a quote of ten hours of work to R&R your intake, for example...
