-I mounted this SE a/c this weekend and it does improve air flow, as evidenced by poor combustion after the mod. I re-autotuned with my Power Vision and all is well again.

-The rubber seal around the stock cover falls off without the back plate to trap it; you might want to pull it off or tack it down with a few dots of super glue.

So this unit is a functional upgrade that looks almost stock (to me) and I like that for now; it's not as clean as stock, as others have pointed out, but I convinced myself I like the open look... Other units can also change the look more aggressively - to each their own (that's what makes mods great)!
