AutoTecknic Carbon Fiber Headlight Covers for the F32/ F36 4-Series, the F80 M3, and the F82/ F83 M4. These eyelids will provide the vehicle with a more aggressive look while maintaining the elegant design of the BMW. These eyelids are made with flexible carbon fiber which is very precise in fitment as it was engineered to follow the shape and curve of the headlights perfectly. These eyelids are made in real 3K twill weave carbon fiber. For installation, just align the eyelids to the hood and bumper then use the included double sided tape and tape it onto the headlights and you are done!
