MST Performance BMW 328i 2014+ (N20/N26) Air Intake Kit & Inlet

MST Performance Air Intake Kit & Inlet for BMW 328i 2014+ (N20/N26) – MST-BW-N2003

If you want more response and a better sound from your BMW 328i, this air intake kit from MST Performance is a straightforward and effective upgrade. Designed specifically for the 2014+ BMW 328i fitted with the N20 or N26 turbocharged four-cylinder engine, it replaces the restrictive factory airbox with a freer-flowing intake system that gets cooler, denser air into the turbo more efficiently.

More air into the engine means the turbo can work more effectively, which translates to improved throttle response, a more direct feeling when you put your foot down, and a satisfying induction note that the standard setup simply cannot offer.

What Does It Do?

The factory airbox on the N20/N26 is designed with noise reduction and cost in mind, not performance. It limits the volume and speed of air reaching the turbocharger (the forced induction system that pressurises air into the engine). The MST Performance kit removes this bottleneck, routing cooler air directly to the turbo inlet via a smooth, less restricted path. The result is a more responsive engine that feels more eager across the rev range.

MST Performance quote dyno-tested gains of up to 12-14bhp (a dyno is a machine used to measure engine power output). It is worth noting that actual gains can vary depending on the condition of your vehicle and whether additional tuning has been applied – but positive improvements are consistently reported on both standard and already-modified 328i’s.

What’s Included?

• Black powder-coated heat shield – helps keep hot engine bay air away from the intake
• Black powder-coated inlet pipe – smooth bore design for improved airflow
• Red dry pleated performance filter – easy to clean and maintain, no oiling required
• Full fitting hardware and step-by-step installation instructions

Key Benefits

The dry pleated filter is worth highlighting – unlike oiled performance filters, it requires no messy re-oiling during maintenance and is straightforward to clean and reuse. The powder-coated finish on both the heat shield and inlet pipe gives the kit a clean, purposeful look in the engine bay and offers good durability against heat and corrosion.

Installation is designed to be accessible, with all necessary hardware and clear instructions included in the kit.
