DESCRIPTION

That exhaust leak you hear in your 911 may actually be the cylinder head leaking where the studs have pulled loose. As Porsche increased displacement of the 911 engine, the different rates of thermal expansion have caused head studs to break or pull out from engine case. These latest aftermarket steel head studs have a thermal expansion rate of approximately the same as the alloy case. Unlike original Dilivar material our studs are made in the USA and are magnetic. We recommend these studs be installed in groups of 12. Do not mix with different studs on same side of engine to insure exact expansion rates.
