You're better off with a DAS scoops, K&N filter, and a charcoal filter.
Thanks NDOG, That is great info on the intake setup. The TMS kit that I was looking at quoted 15hp/and 12 ft-lb without the intake. I am just amazed that I haven't seen anyone that has this mod. I run my car on 91+ so no issue there but I would like to give it a try if I could just find one person that has done it. I was hoping that maybe someone with a 330i has with a dyno run to show some numbers because the closest 4-wheel dyno to me is a haul.
