Agency Power’s Sound Symposer Delete for the Ford Focus ST allows you to remove the artificial engine cabin sound system. This two piece kit features an aluminum block off plate with an o-ring, ensuring a tight seal to the intake manifold. Built into the plate is a threaded 1/4 NPT port that if needed can be used to install a vacuum line. A delrin plug allows you to close off of the factory symposer tube. The symposer delete kit is a must have for the high horsepower Focus ST. Due to the raised boost levels, a strain to the internal diaphragm of the OEM symposer results in a boost leak. Agency Power’s Sound Symposer Delete comes with all necessary hardware for an easy install.
