Its the black thing that hangs down under the intercooler, Are they supposed to be tight??? Mine is really loose....and i think its causing the rattle i am hearing when i am driving.

Any help would be great.

Mine's floppy as hell too, but I think it's normal. I don't have a rattle. If they made it stiff it'd get destroyed the first time you pulled up a little too far in a parking space.

Mine is loose too.....a few friends told me I should remove it...I'm gonna leave it...

Leave it! its made to direct air up into the radiator for better cooling. If you remove it, your car may run hot!

yeah. they are suppose to move. as was said if not the minute you bottom out on a hill or a parking curb its gone. as far as its purpose. it is there to direct more air to the rad/ac condenser/ heat exchanger.
