Description Reviews MINI Cooper S Intake Tube N14 is the tube that goes front the mass air flow sensor to the turbo. On the N14 Cooper S we have been seeing that tube popping off of the turbo side (which is why we created the DT TIF) as well as cracking and or actually snapping off. If the Samco unit is not your speed, then this is the only other option. This is just like the MINI OEM Part but that have a different clamp and works perfect!
