Allows you to use a high flow cone filter instead of stock airbox. Bolts directly to the MAS air adapter and has a 4.5" diameter opening for a cone filter. Good condition, has a little paint overspray, can be cleaned. Should fit any 2G GST,GSX, or Spyder GS & GST. $10, come and get it. PM me.

 

I will purchase that. I'm sending you a PM now.
