If retro inspired aesthetics on a modern functioning muscle car peaks your interest, then look no further than these super durable SpeedForm ABS Plastic Rear Window Louvers. As far as louvers go, this particular set could be classified as subtle. Featuring 8 levels of horizontal slats, the overall profile of these SpeedForm louvers is slimmer than some and less busy looking. They add a smooth tough of muscle to the back of your 2005-2013 Mustang but nothing that screams ostentatious. Convenient and Customizable. One of the strongest assets of these rear window louvers is their ability to be painted to match the exterior of your modern Mustang. This lends itself to a much more intentional design, though the louvers can also be left in their matte black, ABS plastic finish to help them stand out as an accessory of your choosing rather than a purposeful element of your vehicle. The ABS plastic is an alloy that is supremely durable, as well, which will go a long way in ensuring longevity of use. Simple Installation.Installation of the louvers requires only access to basic hand tools. The entire process should take no more than an hour. These louvers have also been engineered to be removed with ease, such that it takes very little effort to move them out of your way when it comes time to clean the rear windshield.
