Airtec Motorsport Big Boost Pipe Kit for Ford Focus ST Mk4
Part of Airtec's expanding Mk4 Ford Focus range, this 11-piece big boost pipe kit improves flow and capacity through the ST's boost pipework, aimed at track or fast road use.
Built from lightweight aluminium for strength under higher boost, with six Pro Hoses silicone joiners and two CNC-machined connectors for straightforward fitting. On the hot side from the turbo, the original 55mm pipework has a restrictive indented section; Airtec's replacement runs a consistent 60mm with no restrictions. On the cold side to the throttle body, the original tapers from 55mm to 63mm; Airtec's replacement runs a consistent 63mm throughout, increasing both flow and capacity. It requires no additional drilling or cutting to fit.
