I just bought what is supposed to be a k&n air filter on ebay and when i got it i looked it over and im pretty sure its a stock air filter in a k&n box :x Can anyone describe to me what a k&n is supposed to look like? Does it actually say k&n on it somewhere? The one i got has the suzuki symbol and has the number 20F0 and it also has sae pa6 stamped on it......... Its for a 2000 Sv650 if that helps
