Direct replacement panel filter from Green - Europe's largest cotton air filter manufacturer.
Trusted and recommended by Impreza drivers all over the world!
The filter has deep pleats that ensure there is a 10-20% increase in surface area to draw more air into the engine. The cotton gauze is made up of a medium and fine layer to trap and hold dirt, dust and moisture particles as small as 0.50 microns. The gauze is held in place by a strong, fine alloy mesh that allows the filter to perform its job perfectly. Complete with a lifetime guarantee.
