MST Performance Air Intake Kit – Ford Focus Mk4 1.5 EcoBoost (2019+)
If you’re looking to get more from your Ford Focus Mk4 1.5 EcoBoost, this air intake kit from MST Performance is a straightforward and effective upgrade. It replaces the standard airbox and inlet pipework with a more free-flowing setup, allowing the engine to breathe more easily – which translates to better throttle response and a noticeable improvement in performance.
On a standard or already-tuned vehicle, restricting airflow into the engine is one of the easiest gains left on the table. The factory airbox is designed around noise reduction and cost, not performance. This MST kit addresses that directly.
What It Does
The kit feeds cooler, denser air more efficiently into the turbocharger (the forced induction unit that compresses air into the engine to boost power). By improving airflow, the turbo has more to work with, which helps the engine produce power more effectively across the rev range. You’ll notice sharper throttle response – meaning the car reacts more quickly when you press the accelerator – along with a more involving induction sound under acceleration.
MST Performance quote dyno-tested gains (measured on a rolling road) of 12-14bhp, though real-world results will vary depending on your vehicle’s condition, tune, and other modifications.
What’s Included
- Black powder-coated heat shield – helps keep hot engine bay air away from the intake
- Black powder-coated inlet pipe
- Red dry pleated performance filter – easy to clean and maintain, no oiling required
- Silicone intake pipe
- Full fitting hardware and step-by-step instructions
Build Quality
MST Performance use quality components throughout. The powder-coated metalwork gives a clean, purposeful look under the bonnet, and the dry pleated filter is a practical choice for everyday use – simple to inspect and clean without any messy oil treatments.
This kit is designed for the Ford Focus Mk4 with the 1.5T EcoBoost engine (2019 onwards). Use the vehicle lookup tool on this page to confirm fitment for your specific model, or check the Vehicle Fitment tab for full compatibility details.
