We recommend this should be carried out approximately every 10,000 km's depending on road conditions...


  • Gently shake the filter to expel the highest possible quantity of surface dust.


  • Spray both sides of the filter with degreaser or wash in warm water with soapy detergent and allow to soak for 10 minutes to loosen the dirt. Do not allow degreaser or detergent to dry on the air filter. 


  • Carefully rinse both sides of the filter with cool low pressure water (tap or garden hose) until all the degreaser / detergent is eliminated. It is normal for the filter to become white at this stage as this is the normal colour for cotton. The darker colour when the filter is new is the filter oil that has soaked into the cotton and has now been flushed.


  • Leave in the sun to dry completely, or if time does not permit, dry under hot air (such as a hairdryer). Ensure the filter is completely dry before next step. Remember, any excessive moisture that remains in the filter will be inhaled into your engine upon the next start-up, which is not recommended. 


  • Filter may be re-oiled by lightly spraying underside with WD40 or any recognised filter oil. Try to establish an even, thin coating, without creating saturated spots. Allow time for WD40 or filter oil to saturate into filter cotton (generally around 10 to 20 minutes) 


  • Wipe out the inside of the airbox before refitting filter.

 

  • Start your engine and feel the difference - Remember... clogged air filters increase fuel consumption by restricting airflow to the engine and therefore can increase fuel consumption by up to 10%.
