do88 Performance Turbo Inlet Pipes (Hybrid 54mm) — BMW M2C / M3 / M4 (F8X)

The S55 twin-turbo engine is fitted with notably restrictive inlet pipes feeding the turbochargers. Reducing restriction on the inlet side is one of the higher-value changes on any performance build, and this kit targets exactly that — the air path immediately before the turbos.

do88 3D-scanned an M3 Competition engine bay to model the available space precisely, then designed front and rear inlets to work within those tight tolerances as a genuine drop-in fit.

Construction

• Rear inlet: custom aluminium pipe with welded CNC-machined turbo connection radius flange
• Front inlet: 3D freeform steel wire reinforced silicone hose with CNC-machined radius adapter
• CNC-machined turbo flanges with flow-optimised radius
• Steel wire reinforced silicone for durability under heat and boost
• Matte black hose clamps included for a clean, factory-stealth look

This is the 54mm inducer version, sized for hybrid / upgraded turbochargers. If your car is running OEM turbos (41mm inducer), order the OEM 41mm version instead — the two are not interchangeable.

Fits BMW M2 Competition F87 (2019–2020), M3/M3 Competition F80 (2015–2018), M4/M4 Competition/GTS/CS F82 F83 (2015–2020), when fitted with 54mm hybrid turbochargers.

Note: installation may require a few screws, nuts and gaskets not included in this kit — see the first page of the installation instructions.
