The OP is clearly advertising for the company showcased in then youtube video. Spectre or w/e.This is general thread they probably started in a variety of different car forums. Pay no attention to it. btw i have a custom spectre intake in my ti hehe.
It doesn't help in terms of performance much neither is the sound great. It does sound nice when the engine is under load and it only cost me around $40 to put together so I'm not complaining.
