Information
Engine head stud, SET OF 12. Dilavar
A 12-piece Dilavar head stud set suitable for partial rebuilds, top-end refreshes, or replacing failed studs on one side of the engine. Provides the same high-strength, heat-stable performance as original Porsche Dilavar hardware. Fits air-cooled 911, 964, and 993 engines.
Fits:
Porsche 911 1965 - 1989
Porsche 964 1989 - 1994
Porsche 993 1994 - 1998
Diagram ref no 11
Aged factory head studs can crack, corrode, or lose tension - especially after decades of heat cycling. Failure of a head stud can cause head leaks, combustion pressure loss, broken cylinders, or catastrophic engine damage. Installing new Dilavar studs ensures proper sealing, correct torque values, and long-term engine reliability.
