im not a fan of the stock air filter, plus a better one will cause my engine to last longer. im thinking of getting the filter that comes stock on the firestorm. http://www2.towerhobbies.com/cgi-bin...&I=LXLGB1&P=&I. It has a dual layer filter, and looks pretty sick[sm=teeth_smile.gif]. And its only 9.29 on towerhobbies. I thought it would be a good upgrade to go along with my new 100cc fuel tank and associated tuned pipe
