Once you enjoy the luxury of the new Vista-Vent you will never be without it. Lets you fly cool and quiet in Summer (no open windows in flight) yet you can cloase it with one twist in cold weather. The Vista-Vent is light yet will not change shape, mounts firmly at four points to avoid cracking windows. Complete control of the cabin air is possible from a direct ram-air breeze to exhaust with a minimum of outside engine noise and no wind whistle. Kit includes instructions, mounting template and all hardware.
