2002 honda civic ex 5 speed....not a mod kinda guy but heard that a cold air intake will improve my mileage as well as give me a modest boost in hp. i bought a V2 cold air induction systems from AEM and and did a little research and now am a little worried that after me a buddy put it on i will be running the risk of the car hydro seizing. is this a real threat? PS AEM doesnt make a blow out valve for the V2 system. any advice or tips are greatly appreciated..... just dont tell me to avoid large puddles. thanx
