I bought them about 4 years ago. They are the factory ones. Porsche changed the mounting design a few years ago. There were aftermarket humps that people were not happy with. Tweeks had some and they had bad reviews. Tweeks pulled them. I never saw the aftermarket ones but someone sent me the instructions. I am out of the hump market and have no idea what Tweeks is now selling.
Makes my artic silver look different than the hundreds of others in my area. Also gives you a 7.5 hp increase.
