This listing is for a Supertec cast aluminum sump cover with included gaskets and magnetic oil drain plug.  iT will fit all late or early pumps in Porsche 911 & 930 engines with sump covers. Cast from aluminum and machined right here in the USA. 

INSTALLATION INSTRUCTIONS:  Install gaskets with gasket sealant, (available at Supertec). For engines with a removable sump screen use two gaskets; one on each side of the screen.  For engines with Carrera style pumps, (screen permanently attached), use one gasket only.  Don't over tighten the drain plug.  Torque to 20 ft/lb or (27 N-m), AND 6 mm nuts torque to 8 ft/lb or 10.8 N-m).  A light-hold "thread locker" product, (such as blue Loctite), can be used for extra security, if desired.
