MST Induction Kit - N55 - BMW M135i / M235i / 335i / 435i / M2 N55 - F2x/F3x/F82 Chassis

Unlock sharper response, addictive turbo sound and proven power on your BMW F‑Series straight-six

Looking for a high-flow air intake upgrade for your turbocharged BMW that delivers real performance and the soundtrack to match? This MST Performance air intake system is a direct-fit, bolt-on upgrade for BMW M135i, M235i, 335i, 435i and M2 models running the N55 engine. It replaces the restrictive factory snorkel with a free-breathing setup designed to improve airflow, sharpen throttle response and enhance induction noise while keeping intake temps in check.

Why enthusiasts choose this intake

• High-flow dry cone filter with advanced nanofibre media for excellent filtration and airflow without the hassle of oiling
• Mandrel-bent aluminium intake tube with a precision CNC-machined MAF housing for stable readings and smooth power delivery
• Laser-cut heat shield in a textured black powder-coated finish to help separate hot engine bay air from the intake path
• Direct fit using factory mounting points and the standard turbo inlet connection for a clean, OE-style installation
• Increased intake sound and turbo spool for that sought-after whoosh and enhanced driving engagement

Dyno-backed gains

On our test car we recorded measurable improvements:

BMW 335i N55: +12.7 bhp at 5724 rpm and +19.8 Nm at 5724 rpm.

Results may vary depending on vehicle condition and supporting mods, but this is a genuine, seat-of-the-pants upgrade that pairs brilliantly with other performance modifications.

What you get in the box

• Performance dry air filter
• Aluminium intake pipe with CNC MAF housing
• Laser-cut heat shield in textured black
• Full fitting kit and hardware

Note: This system utilises the original airbox mounts and the factory turbo inlet connection.
