These louvers are the official Roush Louvers. One of the positives of the louvers is that you can take them off to clean the window, and unlike some scoops you can see through them. You get a template for putting the louvers on and it helps to make sure you dont mess up. They stick to your car w/ 3m tape and the louver attaches to the bracket w/ cheapo screws (I would suggest getting something better). Overall great product.
