MST Performance VAG 1.4 Twincharger EA111 Air Intake Kit

MST Performance VAG 1.4 TSI Twincharger EA111 Air Intake Kit (MST-VW-MK502)

If you own a VAG (Volkswagen Audi Group) car with the 1.4 TSI Twincharger engine, this air intake kit from MST Performance is a straightforward and effective way to improve how your engine breathes. By replacing the restrictive standard airbox with a freer-flowing intake system, your engine gets a better supply of cool, clean air – which can help improve throttle response, bring a more engaging induction sound, and support further performance gains if your car is already tuned.

The 1.4 TSI EA111 Twincharger is a unique engine – it uses both a turbocharger and a supercharger (two different types of forced induction) working together to deliver strong performance from a small capacity engine. The factory intake system is designed with cost and noise reduction in mind, which means it can hold back what this engine is capable of. MST’s kit addresses that directly.

What’s Included

• Black powder-coated heat shield – helps keep hot engine bay air away from the intake
• Black powder-coated 4″ inlet pipe, constructed from mandrel-bent or cast 6061 aluminium for smooth, consistent airflow
• 4″ red pleated nanofiber dry air filter – high-flow and designed for long service life
• Silicone joiner for a secure, sealed connection between components
• Full fitting kit with step-by-step installation instructions

Why Choose This Kit?

The aluminium intake pipe is shaped using a mandrel-bending process, which keeps the internal diameter consistent throughout every curve. This matters because tight or uneven bends can disrupt airflow – something a straight or well-formed pipe avoids. Paired with the nanofiber dry filter, which flows more air than a standard paper element while still filtering effectively, the result is a cleaner, faster path for air to reach your engine.

The included heat shield is a practical addition. Engine bays get hot, and warm air is less dense than cool air – meaning less oxygen per intake charge. The heat shield helps to isolate the filter from radiated heat, keeping intake temperatures down and helping the engine make the most of the incoming air.

Whether your car is running standard power or has already had an ECU remap (a software tune that adjusts how the engine runs), this intake kit is a sensible upgrade. On a tuned car in particular, ensuring the engine has an unrestricted air supply means the tune can work as intended.
