I want to put a crank case breather filter on my civic, will this help performance any or just look cool?

its just for looks.

Won't help performance any, and it'll only look cool for a little while, till oil seeps through it and spatters all over inside. Yes, that'll happen with a breather filter on. ;)

acutally i heard it will hurt performance

you should look into getting a catch can.

oh, ok thanks
