NM Engineering Catch Tank is machined from billet 6061 aluminum alloy and anodized for stealth and added surface durability. The NM tank catches the oil and moisture in the blow-by gas that can cause carbon and sludge build-up in the turbo, intake system and the engine. Every piece of the kit can be disassembled for thorough cleaning and servicing.
Fits the following models with the N18 Turbo engine:
2011-03/2012 R56 Cooper S Hatchback
2011-03/2012 R55 Cooper S Clubman
2011-03/2012 R57 Cooper S Convertible
2011-03/2012 R58 Cooper S Coupe
2011-03/2012 R59 Cooper S Roadster
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.
Some states (like California) have ever tightening requirements for emissions testing and inspections. Always check your local regulations on compliance for street use.
