Review on ARP Performance Head Stud Kit - Porsche 911-930, Model 204-4206 by Art Porras

APR Pro Series Cylinder Head Stud Kit

I bought ARP head studs for a friend's 1991 911 Turbo 3.3 when he was doing an engine rebuild. I recommended these over OEM bolts as OEM bolts can't handle that much pressure and torque. They are much stronger, can withstand more pressure and can be used many times.

Pros
  • Installation Type: Vehicle specific
Cons
  • Can't remember
