MST Cold Air Intake for BMW G20 B48 2.0L (330i / 320i) — Performance-Focused Upgrade

Give your B48-powered BMW a direct performance boost and a smarter, sharper driving feel. The MST CAI is engineered to feed cold, dense air to your turbocharger, improving power delivery, throttle response and induction tone without sacrificing daily drivability.

What it does for your car

• Real-world peak gains of about 8–12 hp (measured around 4000 rpm) and comparable torque increases.

• Faster, crisper throttle response for a more engaging accelerator feel.

• Sportier, aggressive turbo/induction sound under load and on spool.

Key features

• 3.5" high-flow air filter designed for increased airflow and filtration.

• Purpose-built turbo inlet pipe for smoother intake flow and reduced restriction.

• Heat shield to help isolate intake charge from under-hood heat; inlet pipe finished in durable black powder coat.

• Designed to deliver consistently cooler air to the turbo for better efficiency and power.

• Maintenance: clean the air filter every 20,000 km and replace at 60,000 km to maintain peak performance.

• Dyno-verified peak gains: +8–12 hp @ ~4000 rpm.
