Air Filters

If you want to improve engine performance and economy, reduce engine wear and increase engine life then you need a Unifilter from 4WD Systems.

Unifilter uses an open cell foam which is 3-5% product and 95-97% void space. This open cell structure allows air to be pulled through the foam with 40-60% less effort than conventional paper filters.

Sticky filter oil (Filter Fix) which is applied to the filter foam catches all dust particles above 4 or 5 micron. Standard paper filters allow particles of 35 microns or smaller to pass into the motor.

The advantage does not finish there - Unifilter elements are re-useable - at around the normal life of a paper cleaner, Unifilter elements can be washed out with minerals turpemntine, re-oiled with "Filter Fix" and returned to the vehicle. Economically and environmentally - a great concept!
