aFe Momentum GT Cold Air Intake - BMW 340i (F30) - 3.0L Turbo B58
The aFe Momentum GT replaces the factory airbox on the F30 BMW 340i with the 3.0L B58 turbo six. Its smooth one-piece sealed housing has an auxiliary air inlet and a large clear sight window, and keeps engine bay heat away from the filter.
Fitment Note
Suits the 3.0L B58 turbo; aFe also lists the 440i and M140i/M240i with this engine. Not for convertible models, because of the factory strut brace.

aFe Momentum GT intake for the B58 340i, 440i and M240i: overview
An 8-3/4 in (222mm) oval radial filter feeds a dyno-tuned moulded tube, and a high-temperature reinforced silicone elbow makes the connection to the factory breather line. aFe's dyno testing shows up to +9.7 kW (+13 hp) and +18 Nm and up to 28% more airflow than the factory intake.
Options: Pro DRY S is a dry, oil-free three-layer synthetic media that cleans with soap and water. Pro 5R is a five-layer oiled cotton gauze media, each layer finer than the last, for the most airflow. Both versions make the same gains on aFe's dyno.
Installation by a professional is recommended.
