MST Performance Turbo Inlet Kit - BMW M2 (G87) / M3 (G80) / M4 (G82)
The MST Performance turbo inlet kit replaces the factory turbo inlet on the S58 3.0L twin-turbo in the BMW M2 (G87), M3 (G80) and M4 (G82). A larger-diameter inlet pipe with a golf-ball textured inner surface increases airflow into the turbo, improving response and reducing turbo lag. MST rates it at +16 hp and +22 Nm at 5,000 rpm, and up to 16 to 20 hp in its feature list.
It suits both the factory turbos and larger hybrid turbos: a dedicated MST adapter keeps airflow smooth at the stock turbo inlet. The OEM-style quick-connect fitting works with MST intakes and the factory airbox, and a high-temperature O-ring prevents air leaks. It bolts straight on with no modification, and no ECU tune is needed.
Note: MST also lists this kit for the LCI BMW X3 M (F97) and X4 M (F98) from 2022. Pre-LCI 2019 to 2021 X3 M / X4 M cars have a different turbo inlet and are not covered. Installation by a professional is recommended.
