Description Reviews MINI Cooper S Idler Pulley by INA is just like the original but at a lower cost. This is a great replacement pulley when you need it. The only difference we can see is they didn't coat the pulley with a black hard coat, like the OEM one. It's an excellent pulley that we have been using here in the shop for a long time; it's proven to last as long as the original and save the customer money at the same time! This pulley comes with necessary hardware.
