It's from ECS tuning. It's expensive. BUT, It's the same idea as the JCW intake for the R56 but with more room for the air to flow. The JCW filter looks VERY snug. This one looks like enough room for a quite bit more air flow. https://www.ecstuning.com/Mini-2012-Cooper-R56-S-Coupe-L4_1.6L_N18B16A/Engine/Intake/ES2719002/ :cornut:
I wouldn't bother with an aftermarket cold air intake. The stock one flows more than enough air and is engineered for the MINI's engine. Most aftermarket Cold Air Intakes actually reduce horsepower and they are noiser. Spend your money on something else that actually does something , like maybe a rear swaybar.
