air filter for a bimmer

[e36speeder]

is there really added hp for an automatic 318i bimmer if you add a cold air intake filter? is it practical for city driving or will you feel the power on out of town trips only>?

A cold-air intake will help prevent heat soak in traffic, so it'll be noticeably less sluggish when it's really hot outside.

But the amount of power given by a CAI isn't really noticeable if you're driving an AT, as that power usually comes higher up in the rev range. It might feel more responsive, though, but that's it.
