High-Flow Intake System for BMW B38 and B48 Engines - F48 X1, F39 X2, F44 228i

Release extra performance and addictive turbo soundtrack with this CTS Turbo induction system. Designed to work with the factory lower airbox and a dedicated heat shield, this upgrade improves engine breathing, sharpens pedal response and delivers stronger low to mid range pull. Expect real-world improvements of around 9 to 15 hp, with even more headroom when combined with Stage 1 or Stage 2 software.

We have run this kit ourselves and supplied it to enthusiasts across the UK. Feedback is consistent and brilliant: crisper pick-up, smoother airflow, better drivability and a deeper induction note, especially in Sport mode. If you want a premium bolt-on cold air solution that fits right and performs, this is the one.

Why this intake stands out

• High-flow open cone design that mates to the OEM lower airbox for a clean, OE-plus install
• Quicker turbo spool, enhanced mid-range torque and a more engaging sound
• Ideal foundation for remapped cars running Stage 1 or Stage 2 calibrations
• Direct-fit upgrade for B38 and B48 petrol platforms with no cutting required

Key hardware

• 5 inch reusable performance cone filter with 3 inch inlet
• Precision MAF housing engineered for smooth, consistent metering and stable scaling
• Laser-cut heat shield to isolate intake temperatures and pair with the stock lower airbox
