I put over 42,000 miles on my Cobra and would not have a Cobra without wind wings and sun visors. The visors help push the air up just a little to keep in off your face.
You can mount the sun visors in two different positions, one puts the visor a little higher on the windshield.
The wind wings keep the wind out of your right ear. And helps when it rains.
Would not leave home without them.
