Installed on a 2011 MCS. Very easy to install, except on 2011+. You must use your stock tube from the tubro due to two sensors being mounted in the tube. I trimmed down the AEM pipe to fit from the air box to the stock tube. AEM heat shield must also be trimmed on the N18 engine. The oil cap filler is closer to the front of the vehicle and will not allow proper bolt alignment without a trim. Overall outstanding.
