I Just Bought An 07 Civic Si......i Decided To Beef Up The Hp A Bit With An Cai From Injen.....directions Say To Remove The Front Bumper........what Are They Crazy........do I Really Have To Do This

You may have to detach at least one side of the front bumper to remove the lower part of the stock airbox. I had to for my accord.

Thanks

yes you do, its much easier that way and it only takes like 15min to remove the bumper anyway.
