Recently installed the 5 screen set for my 718 Boxster GTS. Each installed securely, and more easily than on my prior 981 Cayman S; impressive! Robust design and manufacturing ensure that road debris won't impact vulnerable radiators and condensers, or cause overheating by accumulated organic debris between them. Once properly installed, the screens remain securely attached. Beyond these practical considerations, the black screen set looks great with the blacked-out-trim specific to GTS models. I highly recommend these for both functional and aesthetic purposes, and wouldn't risk driving without them. Get a set for your Porsche; you won't regret it!
