just get a short ram air intake.. its actually better in the new civic than a CAI (idk why but they are from what K&N and AEM say)... plus a short ram air wont get clogged as easily since it in the engine compartment not below it... and if your from cali or new york make sure the intake has a CARB exempt sticker or it wont pass an emission inspection and you might get a ticket from a cop
