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.\u003c\/p\u003e\u003ch2\u003eBest For\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003eA4 B9 and A5 2.0 TFSI owners adding induction character\u003c\/li\u003e\n\u003cli\u003eStandard or remapped EA888 builds freeing the intake route\u003c\/li\u003e\n\u003cli\u003eReplacing factory intake plastics with aluminium hard pipework\u003c\/li\u003e\n\u003cli\u003eDrivers matching the MAF-equipped intake layout correctly first time\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch2\u003eMatch The MAF, Then Enjoy The Difference\u003c\/h2\u003e\u003cp\u003eAudi 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.\u003c\/p\u003e\u003ch2\u003eKey Specs\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003eManufacturer: MST Performance\u003c\/li\u003e\n\u003cli\u003eProduct Type: Cold air intake system\u003c\/li\u003e\n\u003cli\u003eSKU: MST-AD-A403\u003c\/li\u003e\n\u003cli\u003eVehicle Application: Audi A4 (B9) and A5 (8T) 2.0 TFSI with MAF sensor, 2015 onwards\u003c\/li\u003e\n\u003cli\u003eMaterial: Aluminium intake pipework\u003c\/li\u003e\n\u003cli\u003eIncluded Items: All fittings for a direct OEM-replacement install\u003c\/li\u003e\n\u003cli\u003eFitment type: vehicle and engine specific\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch2\u003eFitment And Setup Checks\u003c\/h2\u003e\u003cp\u003eThe deciding check is the MAF sensor: this kit fits A4 (B9) and A5 2.0 TFSI cars that have one.
