Side effects? You mean torque/power loss down low? I think the dyno for the TSX does show a slight dip at low revs but it is less than the Typhoon and Injen - so less of a "side effect" to use your words. When driving I haven't noticed any power loss down low. I notice more response when I touch the accelerator regardless of RPM.

How much performance gain? Hard to say -- what are your expectations. If you are expecting more than 0.5 seconds faster to 100kph you will be dissapointed. But you will not get that with the Injen either. It is, however, noticeable in day to day driving and in gear acceleration.

Lets put it this way - if you don't mind a loud intake without hesitation go for the Injen or K&N Typhoon. Without doubt that is what I woudl do. But if you still want to retain a relatively quiet cabin you need to look at the Icebox.
Ok thank you for all the information and advice.
