MST Performance Audi A4/A5 1.8 2.0 TFSI EA888 Gen.1/Gen.2 (With MAF) Air Intake Kit

MST Performance Air Intake Kit – Audi A4 / A5 1.8 & 2.0 TFSI EA888 Gen.1 / Gen.2 (With MAF)

If you want more response and a bit more power from your Audi A4 or A5, replacing the standard airbox with a performance intake kit is one of the most straightforward upgrades you can make. This kit from MST Performance is designed specifically for the EA888 Gen.1 and Gen.2 engines (the 1.8 and 2.0 TFSI units found in the B8-generation A4 and A5 from 2008 to 2012), and it replaces the restrictive factory setup with a freer-flowing system that gets cooler, denser air directly to the turbocharger.

The result is improved throttle response – meaning the car feels more eager and reacts more quickly when you press the accelerator – along with a noticeable induction sound that makes the most of the turbocharged engine. On the dyno, gains of 12 to 14bhp have been recorded, though real-world results will vary depending on the condition and tune of your vehicle.

What’s Included

• Black powder-coated heat shield – helps keep hot engine bay air away from the intake
• Black silicone inlet pipe – flexible, durable, and a direct fit replacement
• Red dry pleated performance air filter – easy to clean and reuse, no oiling required
• Full fitting hardware and step-by-step instructions

Why Choose This Kit?

The factory airbox on these engines does a reasonable job, but it is designed with cost and noise reduction in mind rather than performance. MST’s kit opens up the intake path, allowing the turbocharger (the device that forces more air into the engine to produce more power) to breathe more freely. The powder-coated heat shield is an important part of the design – it separates the filter from the heat generated by the engine, helping to ensure the incoming air stays as cool as possible. Cooler air is denser, which means the turbo has more to work with.

Whether your A4 or A5 is completely standard or has already had an ECU remap (a software tune of the engine’s control unit), this kit will complement your setup. It is particularly effective when used alongside other modifications, as improved airflow can help existing tunes perform closer to their full potential.

The dry pleated filter is a practical choice for daily-driven cars – unlike oiled filters, it requires no messy re-oiling during maintenance, just a clean and refit.

Important: This kit is designed for EA888 Gen.1 and Gen.2 engines fitted with a MAF sensor (Mass Air Flow sensor – a component that measures the amount of air entering the engine). It is not compatible with MAF-less setups. Please use the vehicle lookup tool on this page or check the Vehicle Fitment tab to confirm compatibility with your specific Audi before purchasing.
