Don't put that factory windblocker away just because it is summer. With the factory windblocker in place, it keeps the hot air from blowing in on you from the back and makes the air from the airconditioning actually be cool blowing on you in those 90 plus days. Use it all year around! Those of you having the aftermarket windblocker, I assume it doesn the same for you?? I'd like to have a modified version of the aftermarket wb, one that hooked to the uprights of the headrests instead of over the headrests and just covered the gap between the seats just like the regular after market version does.
