MST Performance Cold Air Intake/Induction Kit for BMW 2, 3 & 4 Series B48 2.0T (220i, 230i, 320i, 330i, 420i, 430i) - 3.5in Inlet, Black Heat Shield, Dry Filter, Dyno Proven +12-14 bhp

High-Flow Intake System for BMW B48 2.0-litre Turbo - 220i, 230i, 320i, 330i, 420i, 430i

Give your B48-powered BMW the breathing it deserves. This MST Performance high-flow intake system replaces the restrictive factory airbox with a freer flowing setup that improves engine response, enhances turbo sound and unlocks genuine power gains you can feel on the road.

Independent rolling-road testing has shown increases of approximately 12 to 14 bhp depending on vehicle and supporting hardware. The large 3.5 inch intake tube delivers a straighter, less turbulent path to the compressor inlet which helps the turbo spool sooner and pull harder through the midrange. Expect a sharper throttle, a more eager revving character and that addictive turbo whistle under load.

We run this kit on our own B48 development car and our customers consistently praise the quality, fit and sound. The black powder coated heat shield helps keep intake temperatures in check, while the dry, pleated cone filter offers excellent filtration without the fuss of oiling. It looks purposeful in the bay and performs brilliantly on the road.
