From another thread:
So it sounds like I'm in the clear with the HKS.
I just got my hks intake but I haven't installed it yet. It looks really nice, and inside the filter cage it has plastic fins (they call it "super inner frame") that has the same function as the "air straightner" that everyone is so excited about. I will write a review when I install it this weekend.
