Description Reviews MINI Cooper S Intake Tube N14 is the tube that goes front the mass airflow 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 has a different clamp and works perfectly!
