BMW Windstop 3 series (E46) 323, 325, 330, M3 The BMW 3 Series convertible wind deflector will fit models; 323, 325, 330, and M3 (E46) from 2000 to 2006.
A wind deflector is an essential convertible accessory, the single most effective and unobtrusive way to reduce strong and noisy wind gusts while driving your convertible. Instead of the wind blowing through the cabin of your car, up to 75% of the wind is diverted over the back of your convertible, so you can soak up the elements instead of being at their mercy.
Extend your convertible season: with the wind deflector redirecting the wind over the back of your car, you can drive with top down earlier in the spring and later into the fall and in more comfort all any time.
Drive in peace and quiet: Without the loud rush of wind in your ears, you'll finally be able to listen to music and talk with passengers. The difference is dramatic, especially when travelling at highway speeds.
There are no modifications to your convertible and is designed not to harm your convertible in any way.
The wind deflector can stay in place when lowering or raising your convertible top or can stay in place with the top up or down. Once in place most owners never remove them.
