Audi's B9-era 2.0 TFSI is effortless and efficient - and almost completely silent behind its restrictive standard air box. This MST Performance cold air intake system replaces that box with precision-engineered aluminium pipework designed to accelerate airflow into the turbo with minimal turbulence. This is the version for cars with a MAF sensor, covering A4 (B9) and A5 2.0 TFSI models from 2015 on, and it arrives with all fittings for a direct OEM-replacement install.
Audi built this era of 2.0 TFSI in two intake configurations, so MST engineered a kit for each. With the correct MAF-sensor version fitted, the engine breathes through MST's faster-air, lower-restriction design and answers with an intake note the standard box never allowed - on standard cars and tuned ones alike, built from top-quality components.
The deciding check is the MAF sensor: this kit fits A4 (B9) and A5 2.0 TFSI cars that have one. If your engine has no MAF sensor, use the MST no-MAF version of this intake instead. Inspect your intake pipe for the sensor before ordering, then confirm the part number matches.

Look at the intake pipe after the air box for a wired sensor module, or have a garage confirm it. B9-era 2.0 TFSI cars exist in both configurations, which is why MST make two kits.
Use the no-MAF version instead - the two kits are built around the different intake layouts, so matching the correct one matters.
No - the kit is supplied with all fittings for a direct OEM-replacement install in place of the standard air box.
