What I don't understand is why somebody would pay $600 for a top mount when you can buy a factory Evo or GTR front mount out of Carboy mag here in Japan for about $200. The water sprayers are a good idea though because I even used them on my front mounted setup. It allowed me to relocate the air sensor to free up some room for the racing BOV and some other toys. I would imagine that the top mounts temps would be lower if you would get some weather stripping and make a seal between the underside of the scoop and the top of the IC. It would also then look more like the factory WRX setup. Air would have to go through the IC instead of being able to go around it.
