Valve Guide / EX / Mitsubishi 4G11

EX exhaust valve guide with a total length of 50.05 mm, an outer diameter of 12.05 mm , an inner diameter of 6.6 mm for Mitsubishi 4G11 engines and others. The valve guide is an element whose main task is to guide the valve stem and remove some of the heat from the valve head to the cylinder head. The valve guide holds the valve in the correct position during engine operation and provides the appropriate pressure for correct valve operation. The correct position of the valve relative to the valve seat and the greatest possible accuracy of this fit is desirable, but it should also be remembered that too small a clearance can cause the valve to seize.
