The COBB Sound Symposer Delete Kit for the 2013+ Ford Focus ST offers a simple and effective way to eliminate the factory sound symposer system, giving you a cleaner, more natural driving experience. Instead of piping artificial engine noise into your cabin, you’ll hear the real performance of your turbocharged EcoBoost engine.

Machined from durable 6061 aluminum, the COBB delete plug is finished with a black anodized coating and topped off with a laser-etched COBB logo for a clean, factory-plus look. This kit also provides a usable boost reference port, ideal for future upgrades like a boost gauge, water/meth injection, or aftermarket boost controllers.

The install is quick and fully reversible, utilizing your cars existing hardware. Whether you’re cleaning up your engine bay or prepping for bigger mods, the COBB Sound Symposer Delete is a smart, functional upgrade for any Focus ST owner.
