Fiesta ST “Sound Symposer” Delete

This “Symposer Delete” will replace and block off your stock sound symposer, by so giving you the option to route a vacuum line to your BOV/DV straight from the intake. This gives you a true vacuum source.  

Sound Symposers are designed to give you more noise in your cars cabin making it sound sportier. Unfortunately, these systems can also make your cars motor sound less natural or artificial. Sound symposers can also be a potential problem for boost leaks.
