MST Performance Mercedes 3.0 Twin Turbo V6 Air Intake & Inlet Kit

MST Performance Mercedes 3.0 Twin Turbo V6 Air Intake & Inlet Kit

If you want more response from your Mercedes V6, improving the air intake is one of the most straightforward upgrades you can make. This kit from MST Performance replaces the restrictive standard airbox with a freer-flowing intake system, allowing your engine to breathe more efficiently. The result is improved throttle response, a more engaging induction sound, and real, measurable performance gains.

Designed specifically for Mercedes-Benz models fitted with the 3.0-litre twin-turbocharged V6 M276 engine, this kit has been developed to work with the factory setup and integrates cleanly without major modification.

What’s Included

• Black powder-coated heat shield – helps keep incoming air cool and away from engine heat
• Red dry pleated performance air filter – flows more air than the standard filter and is easy to clean and maintain
• Black powder-coated turbo inlet pipe – replaces the OEM pipe for improved airflow direct to the turbochargers
• Silicone joiner – for a secure, airtight connection between components
• Full fitting hardware and step-by-step installation instructions

Performance Gains

MST Performance’s own dyno testing (testing carried out on a dynamometer – a machine that measures power output) recorded maximum gains of 12-14bhp. These figures will vary depending on the individual vehicle and its current state of tune, but gains are consistent and realistic for an intake upgrade of this type. Whether your Mercedes is running standard or has already been modified, this kit is a worthwhile addition.

Why Upgrade the Intake?

The factory air intake on most production cars is designed around cost, packaging, and noise reduction – not outright performance. By replacing it with a less restrictive system, you allow more cool, dense air to reach the turbos. More air means the engine can burn fuel more effectively, which translates to better throttle response and a modest power increase. The added induction sound is a welcome bonus for those who enjoy a more involving driving experience.

Build Quality

MST Performance are a well-regarded name in the aftermarket intake market, and this kit reflects that. The powder-coated metalwork is durable and resistant to the harsh under-bonnet environment. The dry pleated filter requires no oiling (unlike some performance filters), making it simple to maintain – just remove, clean, and refit.

This kit is designed for 2012+ Mercedes-Benz models including the C400, C450, C43 AMG, and GLC43 fitted with the M276 3.0-litre twin-turbo V6 engine.
