The Yakima Wind Jammer minimizes wind vibration and helps reduce the amount of wind noise produced by your crossbars. The Yakima Wind Jammer simply snaps onto your crossbar in matter of seconds and smooths airflow over the middle of your bar with it's aerodynamic airfoil shape.

Works as advertised. Strange that such a small thing can make such a big difference in rack/wind/noise, but it certainly does.
If you hate that noise your rack makes, then this might be for you. Looked into a fairing but for the cost I went with a windjammer instead. Yes it's an expensive piece of plastic but it works. I've noticed a small increase in gas mileage so to me its well worth the cost.
