High-flow filter and all fittings for a direct OEM-replacement install
Summary
The M133 in the A45, CLA45 and GLA45 AMG was the most powerful production 2.0T of its era, and it rewards every improvement in breathing. This MST Performance cold air intake system replaces the restrictive standard air box with precision-engineered aluminium pipework, supplied with a high-flow filter and every fitting for a direct OEM-replacement install. The result on a 45-series AMG is a harder-edged induction note and a cleaner route feeding a turbo that is always working, covering W176, C117/X117 and X156 cars from 2014-2017.
Best For
A45 AMG owners who want induction sound to match the exhaust theatre
CLA45 and GLA45 drivers covered by the same M133 fitment
Tuned M133 builds where the standard box is the next restriction
Replacing factory intake plumbing with hard aluminium pipework
Feeding A Hard-Worked AMG Turbo
A highly-strung turbo four leans on its intake harder than almost any engine, and MST's design approach - accelerate the air, minimise turbulence, cut restriction - is aimed exactly at that. The high-flow filter and aluminium route give the M133 a cleaner feed under sustained load, and because the kit suits standard and already-tuned cars, it fits everything from showroom-spec to a staged build.
Included Items: High-flow filter and all fittings for a direct OEM-replacement install
Fitment type: vehicle and engine specific
Fitment And Setup Checks
For the 2.0T M133 engine only: A45 AMG (W176), CLA45 AMG (C117 & X117) and GLA45 AMG (X156), all 2014-2017. Non-AMG W176 models use the MST M270 intake kit instead, and facelift-era changes make the year range worth checking. Confirm the part number against your exact car before ordering.

Questions before you order
Frequently asked questions
Does this cover all three 45-series AMG models?
Yes - the A45 (W176), CLA45 (C117/X117) and GLA45 (X156) share the M133 engine and are all in the 2014-2017 fitment for this kit.
Is a filter included?
Yes, the kit is supplied with a high-flow filter plus all fittings, so nothing extra is needed for the swap from the standard air box.
Will it suit a tuned A45?
MST build their kits for standard vehicles and already-tuned cars alike, so it pairs naturally with software work on the M133.
