AEM COld AIr Intake Kits

Hi sorry if this has been covered numerous times but I am a newbie with a 93 HOnda Accord DX, I just put on some new 15 "Konig Traffics with 195 r 60 NItto 460's. I am trying to fix it up nice, and I was wonderign if these AEM COld intake Kits are worth the money, do they really make a difference in HP and performance other than just make a cool sucking noise?
Also I got a big ass battery under the hood will it fit?
OR should I go with the short ram? AND Do I need the bypass valve?
It rains alot here in East Tn///
thanks
