I'm sure there are R&D involved when designing an intake, but for that money, you can buy a procede or an exhaust system. I don't think that price point is going to work with the 335 twin turbos.
It works with the 325/330 crowd, because we know that there's not too much power that can be extracted from our naturally aspirated engines, so Gruppe M can bend us over for 6hp 7tq gain, that gain, to us, is pretty nice for NA engines.
