For those that rely on the Porsche temp sensor, then you may not notice an increase in coolant temp. Reducing the airflow by a much as 60% will increase coolant temps by 5%+ driving around town in 75F+ temps. This is, of course, you have not completed by radiator override mod and keep the 2 fans running full speed. If you do not mind driving around town with engine temops exceeding 215F degrees, then, who cares?

Another alternative is to remove one of the radiators and then you only reduce the cooling by 50% and only have one to clean.

Last time I cleaned them I found a dead bird....seriously.

I had the screens and when my shop removed the bumber to install a 3rd radiator, they found so much crap that got through the screen. And once through the screen, it's impossible to remove without removing the bumper. I removed the screens.
