MST Performance Mercedes Benz A35/A250/CLA250 Air Intake Kit

MST Performance Air Intake Kit – Mercedes-Benz A35 / A250 / CLA250 (MST-MB-A2505)

If you want to get more from your Mercedes-Benz A35, A250, or CLA250, upgrading the air intake is one of the most straightforward improvements you can make. This kit from MST Performance replaces the restrictive standard airbox with a freer-flowing setup that feeds cooler, denser air directly to the turbocharger – helping your engine breathe better and respond more sharply.

MST Performance is a well-regarded name in the aftermarket intake market, producing kits engineered to fit properly and deliver genuine, measurable results. This is not a generic part – it is designed specifically for the Mercedes-Benz MFA2 platform running the 2.0-litre turbocharged four-cylinder engine.

What Does It Do?

The standard airbox on these Mercedes models prioritises noise reduction and meets minimum factory requirements. While that is fine for everyday motoring, it does limit how freely air can flow into the engine. This MST intake removes that restriction, drawing in a greater volume of cooler air and routing it more directly to the turbo inlet. The result is improved throttle response – meaning the engine reacts more quickly and cleanly when you press the accelerator – along with a more noticeable induction sound under load.

On the dyno, MST report gains of up to 12-14bhp over a standard vehicle. Please note: actual gains will vary depending on your vehicle’s state of tune and condition. On an already modified or remapped car, the intake complements existing upgrades well and ensures the engine is not being held back by a restrictive factory airbox.

What’s Included?

• Black powder-coated heat shield – helps isolate the intake from engine bay heat, keeping intake temperatures lower
• Black powder-coated aluminium inlet pipe – replaces the factory plastic pipework for improved airflow
• Red dry pleated performance filter – easy to clean and maintain, no oiling required
• Silicone joiner – connects the intake pipe to the turbo inlet securely
• Full fitting hardware and step-by-step installation instructions

Installation

This kit is designed to be a straightforward bolt-on fitment for the home enthusiast with basic mechanical knowledge and standard tools. The included instructions guide you through the process step by step. If you are not confident working in the engine bay, a competent garage or specialist can fit this in a short amount of time.

This kit is designed to fit the 2020+ Mercedes-Benz A35 AMG, A250, and CLA250 (W177 / C118 platform) with the 2.0-litre turbocharged engine. Please use the vehicle lookup tool on this page or check the Vehicle Fitment tab to confirm compatibility with your specific model before ordering.
