BMW 3 Series (G20 / G21) Titanium Semi-Closed Cold Air Intake System with Clear View | M340i – B58 3.0L Turbo (2019–Present)

Unleash your M340i’s true performance potential with our Titanium Semi-Closed Cold Air Intake System, precision-engineered for the B58 3.0L turbocharged inline-six. Designed with both performance and aesthetics in mind, this system blends motorsport functionality with premium titanium construction and a clear-view lid that showcases the intake’s engineering beauty under the hood.

Constructed from lightweight titanium alloy, this intake system delivers exceptional heat resistance, strength, and a distinct metallic finish. The semi-closed housing design offers the best of both worlds — the free-flowing characteristics of an open intake while still shielding the filter from engine bay heat, ensuring cooler, denser air reaches the turbo.

Expect improved turbo spool, sharper throttle response, and enhanced mid-range torque — performance gains that are noticeable both in daily driving and spirited runs.

Engineered to reuse the factory turbo inlet, this system maintains OEM reliability while simplifying installation. The shortened, reinforced silicone hose reduces turbulence and shortens the airflow path for smoother, more direct air delivery — resulting in faster boost response and reduced lag.
