MST Performance Intake Kit Audi TTRS (8S)/RS3 (8V)/RSQ3 (F3)

MST Performance Intake Kit – Audi TTRS (8S) / RS3 (8V) / RSQ3 (F3) 2.5 TFSI

If you want more from your Audi’s five-cylinder 2.5 TFSI engine, this intake kit from MST Performance is a straightforward and effective place to start. It replaces the restrictive factory airbox with a free-flowing induction setup, giving the engine easier access to cooler, denser air – which is exactly what a turbocharged engine needs to perform at its best.

The result is improved throttle response (how quickly the engine reacts when you press the accelerator), a more engaging induction sound under load, and real, measurable performance gains. MST Performance’s own dyno testing recorded gains of +12.7hp and +21Nm on a suitable test vehicle – though results will vary depending on your car’s specification and state of tune.

This kit works well on both standard and tuned vehicles, making it a solid choice whether you’re running a stock RS3 or an already-mapped TTRS.

What’s Included

• Black powder-coated heat shield – helps keep heat away from the intake, protecting charge air temperatures
• Black powder-coated inlet pipe
• Black silicone intake coupler
• Red pleated nanofibre dry filter – easy to maintain and clean, no oiling required
• All necessary mounting hardware and a full installation instruction guide

Why It Makes a Difference

The standard airbox on these Audi models is designed with packaging and cost in mind, not maximum airflow. Swapping it for this MST kit removes that restriction, allowing the turbocharger to draw in more air more freely. The heat shield plays an important role here too – by isolating the filter from underbonnet heat, it helps ensure the air entering the engine is as cool and dense as possible, which supports better combustion and power delivery.

The dry pleated nanofibre filter is a practical choice for everyday use. Unlike oiled performance filters, it requires no re-oiling – just a clean when needed – and it won’t risk contaminating your car’s mass airflow sensor (MAF), a common concern with some aftermarket filters.
