Apparently kicking or punching carries a little of your momentum while the animation plays, so we can abuse this to push faith a little more under certain vents and/or platforms to be able to neutral coiljump and clip inside.
Kicking works, but since you can chain more than one punch without interrupting the animation, it's best to use punches as the momentum will be carried for a little more.
