Comb RoomThe comb room effect combines a dual delay (room circuit) and a comb filter to make echo reverb type sounds and resonant feedback. The comb filter is in the feedback path of the delays. An envelope follower gives movement to either the comb filter or the room circuit. The comb resonance control in conjunction with the comb return control can create self oscillation. The preamp for the 1 4 input has selectable gain of 10x or 40x and a soft clipping

Nice for the price
Size: For 2003-2006 E46 2-Door, Color: Glossy Black, Size: For 2003-2006 E46 2-Door, Color: Glossy Black
Overall, super happy with it. Didn't expect much since a genuine one is 2-3x the price, but it fits decently (could be better) and isnt super flimsy. It isn't perfect, but its the best youre going to get without buying a genuine OEM one.

It’s just an air filter
Size: CA12290-Premium
It’s exactly how it’s pictured. Not sure what else to say it’s an air filter. I guess it’s doing its job

Not 99.9 %
Size: CA12290-Premium
Only 98% efficient. Says 99.9 in the ad. There is a huge difference between those two efficiencies.
