Hi everybody! My b/f has a 2 dr 2000 civic ex with a nitrous express kit and he will soon very possibly have a prelude engine in it. I know its kinda late for xmas but I was looking to buy him a cold air intake but I don't know which kind and for what? Someone suggested I get him an AEM Civic Si intake and it will work for the engine swap but I wanted some suggestions!! Thanks I'm clueless.
