I/C sprayer? Worth it?
Im a new wrx owner and my 03' is bone stock. In the next few weeks i'll be adding turbo back exhaust, Cobb AP, already have K&N drop in filter. But my question is are the custom I/C sprayers worth it? Ive read the how to articles and articles on other wrx owners making them, however no one ever says anything about the end result. So those of you who know are these worth the trouble or not? Personally i really dont see how it could be that much of a "power" boost?!?! What do you all think, thanks
