My rear spoiler developed a leak so I'm removing the parts to have rebuilt/upgraded. Are these simply push in snaps holding in the air ducts? I understand that some cars may have 10mm bolts in the same place.

 

Yes, those are snap in plugs. You will need a small jewelry screwdriver to push the pin through, to allow removal of the plug. Be careful when pushing the pin. Too much and the pin may be lost in the bowels of your engine bay

 

OK, that worked. I did lose a center plug into the engine compartment. Shouldn't be expensive to replace. Thanks for the advice.
