Sound Symposer Delete Compatible with Ford Focus ST (Natural Aluminum)

The Boomba Racing Symposer Delete Kit is designed for 2013+ Ford Focus ST owners looking to eliminate the factory sound symposer system. This direct bolt-on solution removes the artificial drone noises directed into the cabin, allowing you to enjoy the authentic sound of your engine and exhaust. The kit includes a CNC machined aluminum block-off plate with a precision o-ring for a tight seal, as well as a delrin hose plug. The block-off plate also features a threaded 1/4 NPT port and plug, making it easy to add aftermarket accessories such as oil catch cans or sensors. Ideal for higher horsepower builds, this kit helps prevent boost leaks that can occur when the OEM symposer diaphragm fails under increased boost pressures. Installation is simple and fully reversible, making it an excellent upgrade for both street and track applications.
