MST Performance Ford Focus ST MK4 (2019+) Boost Pipe Kit
If you want more responsive performance from your Ford Focus ST MK4, upgrading the boost pipe is one of the most straightforward improvements you can make. This kit from MST Performance replaces the restrictive factory boost pipe with a higher-flow alternative, helping your engine breathe more freely and respond more eagerly when you put your foot down.
The boost pipe is the pipe that carries pressurised air from the turbocharger to the engine’s intake. The standard pipe is designed with cost and packaging in mind, not performance – so swapping it for a better-flowing option can make a noticeable difference to throttle response and overall engine efficiency.
What to Expect
MST Performance’s dyno testing (testing done on a rolling road to measure power output) has shown gains of up to 5-7bhp on this kit. It is worth noting that results can vary depending on your vehicle’s current state of tune and setup, but the improvement in throttle response and airflow is consistent whether your Focus ST is standard or already running an ECU remap.
What’s Included
- Black powder-coated and silicone boost pipe
- All necessary fitting hardware
- Step-by-step fitting instructions
The use of silicone and powder-coated components means this kit is built to last under the heat and pressure of a turbocharged engine – far more durable than the plastic and rubber used in the standard setup.
