These are the official instructions that came with mine new:
Service every 50-100,000 miles for street use.Service more often in off-road or heavy dust conditions. Note: Exterme fine dust(agricultue/off-road use) will pull the oil from the element.Frequent re-oiling of the clean side might be required...DO NOT BLOW DRY WITH AIR HOSE
Cleaning instructions:
1)pre-cleaning:tap the elent to dislodge any large embedded dirt,then gently brush with a soft bristle brush(If complete cleaning is not practical at this time re-oil the element and reinstall..Remember you can actually use some of the build-up to your advantage,it doesnt cause that much restriction to flow and actually helps better filter the air.)
2)Spray on K&Nair filter cleaner onto the entire element and soak for 10 minutes
3)pan cleaning(this doesnt apply to our filters)
4Hints: NO to the following!
gas cleaning
steam cleaning
caustic cleaning solution
strong detergents
high pressure car wash(or anything high pressure)
parts cleaning solvents
5)Rinse off low pressure tap water flush from clean side to dirty side
6)Drying: Shake and air dry naturally
7) Re-oiling: Always re-oil with K&N Filter oil-either aerosol or squeeze bottle...Spray oil down each pleat with one pass per pleat Wait 10minutes and reoil any white spots still showing...
8)Reinstall.....
