Description

The Whoosh Motorsports SSD Kit is a silicone symposer delete specifically engineered for the 2014 and newer Ford Fiesta ST models. This kit is constructed from multilayer, durable silicone, reflecting the quality of other Whoosh brand silicone products. This modification allows you to remove the artificial sound symposer that is piped into your Fiesta ST's interior. By deleting the symposer, you can achieve a more natural turbo sound and eliminate the subtle "phew" noise often heard during low-speed driving. Furthermore, this delete can help seal potential boost leaks that the OEM symposer might cause when running higher-than-stock boost levels. The process involves removing the OEM sound symposer assembly (parts #3 & #4) and disconnecting the remaining accordion hose at the firewall behind the battery by pressing the connector. A supplied clamp is used for securing the new silicone delete. Customers have reported straightforward installation, with some noting it takes only a few minutes. The delete is praised for freeing up visual space by removing the OEM hose and is considered a worthwhile modification for the price, enhancing the driving experience by allowing the natural turbo sound to be heard more clearly.
