Leaves in your radiator ducts!! Don'tcha just love when you're driving down a backroad, and you see a massive bunch of leaves being blown right in front of your car by a landscaper?...NOT! I just got one of these vacuum extensions that fits nicely thru the vents in my radiator ducts. Sucked the leaves and gravel up in a jiffy! No more trying to pull that crap up with a long stick, or worse, taking off the whole bumper (I'm too lazy to do that now)...
