another way that imo is nice is to buy a 92-95 civic auto zone cold air intake then flip the first pipe around and trim up the second pice and it works well.
I did this a long ass time ago here is a pic of it installed on a d16a1 but would work with a si motor as well.
EDIT: now that I think about it, it may not clear the battery (mine was mounted in the rear). I do not recall if it clears the stocker
