MINI did a great job on 2011 model MCS/Countryman in improving the turbo intake tube by replacing the soft rubber tubing with a full size and rigid ABS plastic one, similar to NM's aluminum/silicone version that we offer for the 2007-2010 MCS & JCW vehicles.
The 'Open-Air-Box' system gives you the abundance and unrestricted 360° of air source compared to OEM's sealed air box with flat filter and tube fed air source. During R&D, we installed temperature probes around the engine compartment and the gauge showed the inside temperature matched the ambient after vehicle speed past 20 mph. And by logging the Mass Air Flow (MAF) sensor also showed that open-air-box intake generated higher volume (gr/sec) of air going through the sensor. So when we had to choose between (a) cooler air at all speed with limited air source, vs. (b) cooler air at 20~ mph. with unlimited air source, the choice was pretty obvious.
This intake is C.A.R.B. approved for emission purposes.
