front bumper/spoiler there are 2 openings for the radiators on each side correct? However, I have noticed that some 911S have a cover on the middle one whereas some do not. If the middle cover is removed there is a radiotor/oil cooler or something behind it...any ideas as why some ocvered and some not? Thanks.

 

It covers the spot where the third radiator gos.
You have a third radiator with X-51 or a car with a Tiptronic

 

Thank you!
