I finished installing my Aem Cai yesterday and I'm very very pleased by the little sucking sound coming from my engine

Install was pretty simple but just had to remove a bunch of stuff and place it all back . I had a friend (civic-type R ) help me out it took us about 2hrs . One thing that I need to do is stop stomping on the gas so damn much b/c i notice my gas tank going more and more towards the big E . Theres a down side to the Cai it seems to be rubbing against my hood some how

but hopefully I'll get this problem fixed soon .
