Big Mouth® high performance washable filters have a special filtering element made up of several layers of pure cotton with a particular mixture of oils and resins which guarantee a high filtering power and an air flow well above that of normal paper or sponge filters. This superior performance is guaranteed for long distances even on dusty roads to ensure maximum power from your engine with minimum fuel consumption and therefore considerable savings. The filter is already oiled and ready for use.
Maintenance should be carried out approximately every 10,000klms depending on road conditions. Gently shake the filter to expel the highest possible quantity of surface dust and if you have been driving on dirt roads use an air compressor to blow out any large dust particles. Spray both sides of the filter with degreaser or wash in warm water with soapy detergent. Carefully rinse both sides of the filter under running water or the hose until all the degreaser/detergent is eliminated. Leave in the sun to dry completely, or if time does not permit, dry under hot air (such as a hairdryer). Filter may be re-oiled by lightly spraying underside with WD40. Wipe out airbox before refitting filter.
