• BMW X3M F97 S58 3.0L Twin Turbo (2022, 2023, 2024, 2025), LCI models only
• BMW X4M F98 S58 3.0L Twin Turbo (2022, 2023, 2024, 2025), LCI models only
• Note: F97 X3M and F98 X4M fitment is LCI (facelift) 2022 and later only. Pre-LCI X3M and X4M use a different turbo inlet design and are not compatible with this kit
• Note: Compatible with the stock intake system and aftermarket intakes that retain the factory inlet connection size. Not compatible with aftermarket intakes that replace the inlets entirely

Fitment Note: These high flow inlets replace the factory turbo inlet pipes on the S58 twin-turbo engine across the G8X M2, M3, M4 platform and the F97/F98 X3M/X4M in LCI configuration only. The pre-LCI X3M and X4M use a different inlet design and are not covered. These inlets are compatible with the factory intake system and aftermarket intakes that retain the factory inlet connection size. They are not compatible with aftermarket intakes that replace the inlet pipes as part of their design. Sold as a set of 2, one per turbo.

Specs and Features

• Sold as a set of 2 inlet pipes, one per turbocharger
• CNC billet aluminum construction with precision machined flanges for strength, heat resistance, and smooth unrestricted airflow
• Larger internal diameter than the factory turbo inlet pipes, reduces intake restriction and helps the turbos spool faster and breathe more efficiently across the RPM range
• Optimized geometry for improved airflow and reduced pressure drop between the intake and turbocharger inlets
• Direct bolt-on installation using factory mounting points and hardware
• No tune required
• Compatible with factory intake and aftermarket intakes retaining stock inlet connection size
• Ideal for stock turbo vehicles and tuned setups seeking improved airflow efficiency

Pairs well with:

• MAD Valved Axleback Exhaust for BMW G80 M3 / G82 M4 (2021-2025) Opening up the intake side with these high flow inlets and the exhaust side with the MAD axleback addresses both ends of the S58 with the same brand's engineering approach, and the axleback's +5 HP and +5 lb-ft gain stacks directly on top of the airflow improvement from these inlets.

The factory S58 turbo inlet pipes are one of the first documented restriction points on this engine, particularly at higher power levels where the turbos are working near the top of their compressor maps. The factory design creates a pressure drop between the intake and the turbocharger that makes the turbos work harder than they need to. These MAD inlets replace that with a larger internal diameter, CNC billet aluminum design that reduces that restriction and lets the turbos breathe more efficiently. No tune is needed since these are a direct physical swap with no sensor changes, and they're compatible with the factory airbox as well as aftermarket intakes that keep the factory inlet connection size in place. If you're running an intake that replaces the inlets entirely as part of its design, confirm compatibility before ordering since those setups use a different connection at the turbo.
