I've seen this lip spoiler before also, and am not sure how I feel about it. Maybe color matched it might look better, but I haven't felt like spending the money to buy one and get it painted to find out that I don't like it. I personally think that if I didn't buy an OEM spoiler, I would want an aftermarket one to be more of a duckbill or wald type spoiler. Another thing to keep in mind is that the only thing that is going to be holding this lip spoiler onto your car is double sided tape.
I kind of liked the spoiler they made of the Galpin Auto Sema TLX:

One last note, if you do decide to go with an OEM spoiler, they have been having trouble with the fitment. Many people are reporting gaps after having it installed at dealerships. Acura supposedly re-made the installation template, but I think some people are still reporting problems. Over at Acurazine there is an entire thread on it
