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.\u003c\/p\u003e\u003ch2\u003eBest For\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003eM3 and M4 Competition owners upgrading the S58's intake path\u003c\/li\u003e\n\u003cli\u003eTuned S58 builds where factory inlet pipework limits the plan\u003c\/li\u003e\n\u003cli\u003eReplacing standard plastics with precision hard pipe that holds shape\u003c\/li\u003e\n\u003cli\u003eCompleting an intake setup alongside filter and air box work\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch2\u003eThe Restriction Between Box And Turbos\u003c\/h2\u003e\u003cp\u003eInlet 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.\u003c\/p\u003e\u003ch2\u003eKey Specs\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003eManufacturer: MST Performance\u003c\/li\u003e\n\u003cli\u003eProduct Type: Inlet pipe kit\u003c\/li\u003e\n\u003cli\u003eSKU: MST-BW-S5803\u003c\/li\u003e\n\u003cli\u003eVehicle Application: BMW M3 Competition G20 G28 G80 and M4 Competition G22 G82, 3.0T S58, 2021 onwards\u003c\/li\u003e\n\u003cli\u003eIncluded Items: Direct replacement inlet pipework for the factory part\u003c\/li\u003e\n\u003cli\u003eFitment type: vehicle and engine specific\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch2\u003eFitment And Setup Checks\u003c\/h2\u003e\u003cp\u003eFor S58-engined Competition cars from 2021 on: M3 Competition (G20 G28 G80 codes) and M4 Competition (G22 G82).
