As far as for me, I love takeda for 2 things, price and sound

Its so much cheaper than Injen, its the same style (short ram) and it sounds very aggressive when you step it down. Only complain I have about this intake is that the 2 logo on the intake is vinyl stickers and they peel off after awhile.... Thus its not good for show car purposes.... but if you don't care about your engine bay dress up, its one of the best intakes out there
On a side note, takeda intakes are known for one of the best BMW aftermarket intake mfg and their stuff is made in US instead of China
After all, I would suggest you ask forum's local members to show you the sound difference so you can better decide. As far as power gain, you won't be able to feel it with that mod along (without tune). I hope this helps
Enjoy!
