helmholtz chamber - 550 SE
Anybody with a 2004 550 Spyder...can you tell us if your intake has a helmholtz chamber if any kind? What does your air box look like and is the engine bay wall(s) different from previous 986s
Detailed pictures of the engine bay would be appreciated as well.
Just wondering if the 987 air box muffler we are shaving off is there for performance at all
