BMW M3 Competition G20 G28 G80 3.0T S58 2021+; BMW M4 Competition G22 G82 3.0T S58 2021+
Included Items
Direct replacement inlet pipework for the factory part
Summary
On an M3 or M4 Competition, the S58's factory inlet pipework is the restrictive link between air box and turbochargers. This MST Performance inlet pipe kit replaces it with precision-made high-flow hardware, engineered as a direct swap for the standard part. It is the focused upgrade for S58 owners building the intake side properly: better flow where the twin-turbo six actually draws its air, on G80 M3, G20/G28-coded cars and the M4 Competition G22/G82, from 2021 on.
Best For
M3 and M4 Competition owners upgrading the S58's intake path
Tuned S58 builds where factory inlet pipework limits the plan
Replacing standard plastics with precision hard pipe that holds shape
Completing an intake setup alongside filter and air box work
The Restriction Between Box And Turbos
Inlet pipes rarely get the attention filters do, yet on a twin-turbo engine they carry every gram of air the turbos swallow. MST engineer this kit as a direct high-flow replacement for the restrictive factory part, using the top-quality components their kits are built with. For a car as capable as the Competition-spec M3/M4, it is the unglamorous upgrade that makes the rest of the intake work properly.

Fitment And Setup Checks
For S58-engined Competition cars from 2021 on: M3 Competition (G20 G28 G80 codes) and M4 Competition (G22 G82). Standard 3 and 4 Series B58 models use different MST kits, so verify your car is the S58 Competition and confirm the part number before ordering. If you are planning filter or air box changes too, fit them in the same session to save duplicate strip-down time.

Frequently asked questions
Does this fit a standard M440i or 340i?
No - those use the B58 engine. This kit is engineered for the S58 in the M3 and M4 Competition from 2021 on.
Is this a complete intake system?
It is the inlet pipe stage: a direct high-flow replacement for the restrictive factory pipework between the air box area and the turbos, and it can sit alongside further intake upgrades.
