NTZ Micro Filtration offers the most advanced patented micro filtration products for the fleet market. NTZ is recognized Tier 1 and Tier 2 to the automotive industry worldwide and specializes in high efficiency depth filtration for advanced powertrain systems.The NTZ-filter is a bypass oil-micro filter. It is applied on combustion engines and transmissions as an extra filter, along with the existing full flow filter, in order to achieve superior filtration of the lubricating oil. Because of this, the oil, as well as the engine/transmission remains much cleaner. The result is that engine wear can be reduced dramatically, engine performance will increase, while at the same time oil change / service intervals, dependent on operating conditions, engine type, and oil quality can easily be extended to 2 ~ 3+ times your normal oil change interval. These filters are also recommended for transmission applications.
