Cylinder Head Stud Set 911 Dilavar 993 Turbo

The 993 Turbo Version is the last developmental stage of the Dilavar 911 Cylinder Head Stud and the only Stud you should be considering for your 911 Performance Build or Stock Dilavar Head Stud replacment.

The more performance oriented your 911 engine build is the more important it becomes to use these Dilavar Head Studs and get away from the stock steel studs. They have a similar expension ratio to aluminum of the cylinders and therfore avoid cylinder head clamping down, bowing/deforming of cylinders and blow by.
