K&N and Volant both use the same filter material. K&N cleaning kits are the easiest to find. I got mine at AutoZone. I also had WildWheel make me a transparent Volant cover. It looks cool and I can inspect my filter without removing the lid. When cleaning the filter its nice to have a utility sink to rinse the filter. Rinsing with a garden hose could kill you grass.
K&N says not to use high pressure air or water as it can damage the filter. How often depends on your enviroment..like dusty back roads, sand etc. I do mine about every 20,000 miles.
