y not just take off the air filter b4 u got for a run with the mazda6, it will damage ur engine for sure, but if u really lookin for better performance........keep in mind that itz free, n nth is free in this world...............
if u dun wanna damage ur engine that much, then open ur trunk n c wat u can take out( for example: spare tie, jack, tools, mat etc), clean it out, that saves atleast 20lbs there, then do an oil change w/ mobile1 oil, n pump the air in the tire to max it can to reduce the friction of the tire............thatz pretty much it........n dun forget to fill up the tank w/ 94 + octane booster, it does help..........<--more gas = not as much air in fuel resulting insufficient fuel to burn..........:lol: :lol: :lol:
BTW, Mazda6 V6 aint that fast, coz the areodynamics n the weight, n remember itz a ford, it might break down b4 the run starts....:lol: :lol: :lol:
