Proflow Turbo Bellmouth-style Aluminium Black Velocity Stack 4in.

Part Number : PFEBM4

Our high efficiency bellmouth-style velocity stacks increase air velocity into the turbo by decreasing the inlet diameter towards the compressor housing. This dramatically improves airflow to the turbo and provides a more consistent power-band. They are manufactured from spun-aluminium and come in 3 different sizes to cover a wide range of turbo sizes.
