what exactly are you asking? :confused:

what is the top one? (since the sticker gives away what the bottom one is)

they look very similar and i'm sure your butt dyno wouldn't be able to tell the difference

The top one is made by K&N, the bottom one is made by ECIS. Please read #6 on our FAQ page for more info.

why do both of them bend away from where the air comes in?
It is away from one of the air feeds, but the hood completes the "box" concept which keeps the air near the filter (to draw from).

Secondly, a proper intake should have a length of mandrel bent tubing, with a proper bend, BEFORE the hfm for straightening and channeling of the incoming air.
