Oil Catch Can Kit | 2011-2015 | R55-R59 | N18B Engine | 56-310306


Fits all R55-R59 MINIs with N18 1.6 Liter turbocharged engines.

Filter out the performance robbing oil mist in your crankcase vent system. This oil mist creates an oil film in critical places throughout the engine-- such as the intercooler-- where clean surfaces are critical to maximized heat transfer and on your MAF sensor (Mass Air Flow) where the film will cause the sensor to send a false signal to your ECU killing performance. Install an M7 coalescing Oil Catch Can System today. Engineered....Tested....& Proven to Perform!  The M7 Catch can is the best engineered and best fitting system available for the MINI....PERIOD!

    The NEW & IMPROVED Oil Catch Can kit for MINIs equipped with the N18B engine comes with a "designed-to-fit" stainless steel bracket, mounting hardware and pre-assembled hoses. Installation is super easy...no drilling and no special tools are needed. NOTE: This kit will fit on the firewall directly behind the outlet of the stock or aftermarket airbox.  It uses the factory tab located on the firewall. Fitment is guaranteed.

    Oil seperation is accomplished inside the can using coalescing seperation technology.  This system combines the small mist droplets coming from the engine crankcase into larger and heavier drops.  Gravity then pulls the heavy drops out of the flowstream and into the reseviour for collection. The cleaned airflow is then directed out of the OCC system and into the intake hose for recirculation.  Test results show up to 95% of the oil is removed from the PCV system with the M7 system in place. Baffes are not required because the airflow within the PCV system is very low. (less than 1 CFM)  At these extreamly low flow rates baffles would not seperate mist. Baffles are met to redirect flow withing a closed chamber. (as in in a muffler)

    "Forum experts and social hysteria" say an OCC is not needed but we beg to differ. Why do so many MINI owners suffer from carbon buildup on their intake valve? The answer is oil being recycled through the intake tract to be burned. With the M7 Oil Catch Can, your MINI Cooper's engine will be protected from excessive oil and hydrocarbon buildup which leads to performance-hindering oil film and sludge along your intake tract, on your engine control sensors and on your engine's intake valves.

    Because the 2007 & up MINI is a direct injection engine, the intake valves do not benefit from the cleaning action provided by the gasoline as in older port injection engines. Now all the oil blow-by burns and sticks to the intake valves and builds up into a flow choking hydrocarbon mess.  The end result is loss of power and a very expensive repair bill. This oil film & sludge can appear in other critical places throughout the engine-- such as the intercooler-- where clean surfaces are critical for maximized heat transfer and on your MAF sensor (Mass Air Flow) where the film will cause the sensor to send a false signal to your ECU killing performance.

    By capturing excess oil vapor and particles, the M7 Oil Catch Can ensures that oil film and sludge will not become a factor in your vehicle's performance. If you don't think your engine is pumping oil back through your intake system, remove the breather tube and look at all the oil!.  The breather tube connects directly to you intake hose and directs this oily mess back through your engine to be burned.

    All hoses, brackets, clamps, necessary fittings and easy to follow detailed step-by-step instructions are included, including an oil drain plug and an easy to view sight tube. The sight tube lets you know the amount of oil in the can. The hoses are high quality "Made in the USA" automotive grade designed to withstand the rigors of the under-hood environment and to not degrade when exposed to oil. Beware of other "low cost" catch can systems that use silicone hoses because oil and silicone are not compatible. Silicone hoses will will eventually deteriorate and make an absolute mess of your engine compartment.

    Perfect product
    Would Recommend
    High quality parts all around, works as intended and was super easy to install. Would highly recommend.

    I left my lines a little long for a future application and one of them is a few inches above the turbo which made it too hot to touch so for longevity of the hoses I would recommend a turbo shield.

    Great product

    Very nice product. Was very easy to install and it looks great on the car.it is functional and it does what its design to do. Definitely recommend that other mini owner to get this product.it catches the oils and prevent it from getting into you intake. I love that it has a dip stick to check it level. Look like a part of the car, and doesn't stick out like a sore thumb. Review by Col34761 (Posted on 11/26/2020)
