I use this air filter for my 2015 MINI Paceman and, being sensitive to the car, I can notice a slight gain in HP plus there is a bit more audible noise from the turbo. These filters are great and require virtually no maintenance. The install is a breeze as well. It is probably the easiest mod you can do with the most amount of gain. Ordering through K&N also is simple and shipping was ultra quick. You really can't go wrong with this product.
