[wan syahmi]

hi, wanna ask to anyone who know for the spec for the valve spring. iam actually want upgrade from standart valve spring to m3 valve spring. my cam is hiop hi cam, so its better to change better spring and my mileage clock at 260000, so the spring strengh is already low. so anyone know my engine can fit m3 valve spring or not. tq
