Seal the interior of your 2015-2023 Mustang from water and debris with these new door jamb rubber plugs. From the factory, Ford used a sticker to seal off an open hole on both exterior a-pillars below the upper door hinge to keep the elements out. This seal can be found by opening the door and looking at the gap between it and the fender. This factory seal is known to peel up and come off causing excess water to enter the interior. This new rubber plug kit replaces those stickers utilizing the correct dimensions allowing for a simple install by cleaning away the old sticker and popping in the new rubber plug. Constructed of black rubber material, this door jam plug has been manufactured to the correct diameter of the a-pillar door jamb opening and will last much longer than the problematic OE sticker. We've come up with this great solution for the leak to maintain a proper seal utilizing these plugs in your S550 Mustang to prevent this leak from recurring!
