Ummm what are these for?

Anyone know what the point of this vent thing is on the trunk? It did have there floppy rubber things, but i took them out cause they're noisy with a sub.

They're probably the vents that permit air flow through the cabin when the windows are closed. They usually locate them in a low pressure area (relative to the higher pressure inlets) at the back of the car to help draw air out of the cabin when driving.

Are they located behind the plastic rear bumper cover?

About the only problem I could see from removing the rubber flaps is you may get a bit of dust in the trunk. Or possibly critters

[Lirueil]

Yes they are.
Lol I assumed that was their purpose.
thanks.

the design also keeps water out of the trunk.. but yeah, its for air flow. also pressure relief (ever hear the story of old camaros with t tops where if you slammed both doors at the exact same time glass would shatter?

[Lirueil]

haha, no I have never heard of that.
so it's really not a big deal to have those rubber floppy things off

[MetroMPG]

Except for the critters!

so water and critters in the trunk don't bug you? I wouldn't want critters, but with the water, if you're in deep enough water to where that's submerged - you've probably already lost the engine and have other big things to worry about...

[petrified.rabbit]

its not about submersion. it the rain splash up by your tires, and the rain the runs down your quarter panel.

the rubber flaps act like shingles on a house, but are flexible to "flap" to let the hotter air out of the car. And let quick pressure changes in the car be released. (like camaro breaking glass) or simpler things like if you slammed your car door and the car was actually sealed as well as is should be (without those flaps) your ears would probably pop like in an air plane..

they simply should remain there. if they are vibrating or something, try spraying them down with white lithium grease inside and out, this will weigh them down, to prevent vibration, but allow them to keep water out, and still be free to move for the pressure changes..

[Lirueil]

crud, well I've already taken them out, I'll see tomorrow if they're able to be reinserted lol.
But ya they only vibrate loudly because of the 2 12" subs in the trunk.
Thanks for all the info.

[serega12]

This may sound like a stupid question, but you did check that vibration went away, right? And is it the rubber flaps or the housing they sit in? If its the housing you could try siliconing it around the perimeter in there... just my $0.02
