A vehicle's regular oil filter is a full-flow filter. This means that all the oil pumped by the engine must pass quickly throught the filter before it reaches the engine. This high flow demand limits the size of particles conventional filters can effectively remove.

Particle Size is measured in units called microns. A good full-flow filter will effectively remove particles down to about 25 microns. But studies have shown that over 60 percent of all engine wear is caused by particles in the 5 to 20 micron range.

AMSOIL By-Pass Oil Filters remove particles down to less than one micron, keeping the oil free of virtually all wear-causing particles. The Dual Remote system combines both full-flow and by-pass filtration on one convenient mount. With this system, all the oil is super-filtered more often.

The dual remote mount is designed to make filter changes easy and convenient. It accomplishes this by using a remote filter mount that is easily installed in an accessible area of the engine compartment. This heavy-duty machined aluminum mount is connected to the engine block by two oil lines and a special spin-on oil filter adapter.

The machined aluminum spin-on adapter replaces the engine's full-flow filter, using thread adapters that allow the dual remote system to fit about 98 percent of all car and light truck applications in the United States. Ports in the mount provide both a source of oil and a place to return it to the engine.
