Description Reviews MINI Intake Duct is a stock OEM part that goes from the supercharger to the throttle body on all gen 1 MINI Cooper S's (R52 & R53). Over time they can crack just because they are plastic or if you're replacing something in the engine bay and the tab breaks off that holds it onto the supercharger. We recommend replacing the gasket at the same time, as well as look at the bypass valve. You will also need a #28 clamp to complete the job.
