S58 G80 G82 G87 High Flow Turbo Inlets

The last restriction before the turbos on the S58 is the factory plastic inlet elbows. They’re narrow (about 45 mm at the compressor), they heat-cycle and go brittle, and they choke airflow just as boost demand climbs.

These inlets replace those elbows with larger-diameter CNC billet / mandrel-bent aluminium pieces so both turbos can actually breathe. Finished off with a powder coating for maximum heat management of IATs 

What you get

•  Larger turbo-side bore 60mm & 70mm

•  Smoother internal path, less turbulence into the compressor

•  Quicker spool and sharper throttle response

•  Stronger mid-to-high RPM pull

•  Aluminium construction that won’t crack like the OEM plastic

•  Direct bolt-on — factory mounting points, no cutting

•  Works with the stock airboxes and most aftermarket intakes that keep the OEM inlet connection size

•  No tune required to run (gains still stack with a map)

Fitment

•  G87 M2 (2023+)

•  G80 M3 / M3 Competition (2021+)

•  G82 / G83 M4 / Competition / CS / CSL (2021+)

•  F97 X3 M LCI 2022+ only

•  F98 X4 M LCI 2022+ only

Pre-LCI X3 M / X4 M (2019–2021) use a different rear inlet — confirm build date before ordering.

DIY friendly for a mildly skilled enthusiast. 

Pair these up with a set of intakes to get the best sounds out of it!
