Depends on your budget and what you want it for to be honest. For a 182, if you are after more power/the best availabl then you want an ITG Maxogen (Not cheap!) If you just want a nice noise then any after market induction really! I quite like the look of the stainless steel mesh induction kits (like the powertec) but can't get one for my engine. I'm undecided what to get for mine at the minute, K&N, Pipercross or go to that Raid.
For you, if it's between the powertec, Green and Raid Hp then I'd possibly say go for the Raid carbon fibre or the powertec. Certainly the Raid ones aren't going to be any worse than the other two
