These metal mesh grilles (left and right) will help protect your 2012-2016 Porsche 911 991.1 Front Side Radiators from road and track debris. These grilles fit the Porsche 991 991.1 Base, S and 4S models (choose model when ordering). These grills fit both cars with and without parking sensors.

These grills will work with both.
