Pop Charger Whistle

[smockers83]

I know its not something to worry about and I've searched the forum, but does anyone know where/how this whistling occurs? Is it a leak of some sort?

Its completely normal and its just the sound of an intake filter without any baffles.

It's normal. Has nothing to do with pop charger as much as it is actually being able to hear it now that stock intake is gone. It's just the sound of air being sucked in quickly. So in all honesty, it's a good sign because it means the popcharger is doing its job.

Thanks, I kept hearing it was normal but had to ask anyhow since usually when things whistle there's a gap where air is escaping. So if this is the way it sounds without baffles, the Z doesn't sound like this stock does it?
