Description Reviews MINI Cooper S Intake Tube for the N18 is the tube that goes front the mass air flow sensor to the turbo. The aftermarket finally caught up and made an LCI tube. 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 completely off. This is a quality aftermarket part that we have just started using at the shop. So far no issues with quality, fitment is spot on, and they price savings is nice!
