None of my local Suzuki dealers have air filters for the GS500E in stock.. And both of them want around $28 to order it.. which seems a little excessive for a paper air filter. Anyone sell these online that I can buy or have a local dealer they can get one from for a decent price? I can paypal you the price + shipping.

K&N is a good alternative. It will last forever. This is the stock version, it wil increase air flow a bit, but not require jetting. It can be used with jetting as well too. That is the nice part.
