Agreed.
That being said, my car makes the same noise occasionally after being driven for a while. It is more frequent than the injectors (slight pulsing, sometimes just a constant high-pitched sound) and sounds very different than the clicking. I've owned two wrx's before, and while I will be the first to say that boxer engines are naturally noisy, this noise doesn't sound familiar. However, I haven't noticed any performance or idling issues.
