Description The Ford Fiesta ST180 Symposer Delete consists of a billet aluminium blanking plug to replace the symposer device from the OEM cold-side boost pipe. This blanking plug fits into the cold-side boost pipe extension hose (See diagram: blue, #4) and will replace #3 on the diagram. The symposer delete kit has 2 options: Remove just the symposer (blue, #3) and leave the remaining loose hose that connects into the cabin in place. Remove the symposer and the hose (yellow, #1) that connects behind the battery box. This will require you to remove the intake airbox and the battery box to gain access to the end.
