Question? I got the evo2 and evo3 both IDM, great engines! the 2 comes with a suplement on the manual that says "the piston rod need to be replaced each gallon of fuel used" the 3 doen't come with this paper, is still the same rule with the evo3? or is only on the 2. any way i purchase 2 rods for replacing it for 301 race.
