It replaces the restrictive standard air box with precision-engineered aluminium pipework designed for faster, smoother airflow into the turbo, giving the A4 or A5 a cleaner intake route and an induction note the standard car never offers. Four no-MAF applications from 2015 on are covered, 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 whose cars run the no-MAF intake layout\u003c\/li\u003e\n\u003cli\u003eQuattro drivers covered by the same fitment\u003c\/li\u003e\n\u003cli\u003eStandard or remapped EA888 engines freeing the intake side\u003c\/li\u003e\n\u003cli\u003eSwapping factory plastics for aluminium hard pipework\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch2\u003eThe No-MAF Route Done Correctly\u003c\/h2\u003e\u003cp\u003eFitting the wrong configuration is the classic B9 intake mistake, which is why MST split the kits. With the no-MAF version matched to the right car, the engine gets MST's faster-air, lower-turbulence design and the driver gets the response feel and intake note the restrictive standard box hides.
