The NM Engineering Catch Tank kit also features custom tooled silicone hoses with Fluorosilicone internal lining developed specifically for petroleum base application. The lack of adapters on this kit ensures smooth, unrestricted, and completely sealed vapor delivery through out the system.
MINI dealer service charges 5-6 hours ($600-700) to clean your intake port from carbon build-up caused by the oil/moisture circulating back into the internal. This procedure is 'recommended' around 60-70,000 miles, after your warranty expires.
