I am constantly amazed at where bikers will spend money. I see fellow bikers spend thousands on chrome whatzits and whatnots but neglect one of the most important parts on their bike- the lowly air and oil filter. Simply assuming that all filters are the same, or the filter labeled by the bikes manufacturer is good enough, or worse yet, that the manufacturer's filters are the best you can get is a very risky mind-set.
Do the research. Check the brands. Good filters are not cheap. You get what you pay for. You would never use a product that would scratch or dull that fine chrome, but that is exactly what happens to engine components when you cheat on filters. No motorcycle manufacturer makes filters. Period. They buy them based on lowest bidder price and label them. They have no interest in quality and frankly, profit from your use of inferior filters.
As I said, do the research and check the brands. The best filters are made by companies that CARE about your bike. Purolator, Wix, K&N, Green and a few others have been in the filter business for years based on quality products. Others have also been in business for years and make a crap product (i.e. Fram) because they spend big money on advertising. When shopping for a filter, don't shop price, shop quality. Most companies even offer chrome filters to match the whatzits and whatnots you bolted on already!
