Wind deflectors let you get more fresh air passing through the vehicle without being buffeted in the face by wind. For a vehicle with no air conditioning - such as LRO's Discovery 1 - this makes hot summer drives more enjoyable. They don't eliminate the breeze altogether, but they do take off some of the harshness, and rain is also deflected quite effectively - so you can get fresh air on a wet day without getting soggy.

They come as a four-piece set for a five-door. as this vehicle is a three-door, the two deflectors for the rear doors are unused - but you could turn them into handy storage troughs for maps...

Attaching them is dead easy thanks to a strip of 3M adhesive on the back, and no drilling is needed. After eight months they show no sign of peeling off and the plastic is in as-new condition.
