  • Direct Fit Replacement - Fits all Subaru Impreza WRX & STI TURBO EJ20 2.0L and EJ25 2.5L DOHC Turbo Engines. Engineered to unleash more performance out of your vehicle. Please see vehicle compatibilities tab above to ensure accurate fitment.
  • Ultra Strength - Xotic 7200 material properties allow for far greater tensile strength compared to 8740 chromoly steel head studs. Rated at 220,000 psi tensile strength. Threads rolled after heat treatment for optimum fatigue strength. Ample clamping strength prevents cylinder heads from lifting.
  • Easy Installation - Broached stud ends install & make cylinder head removal easier. Installation manual is included with drawn diagrams to ease the installation process. Head studs are designed to retain cylinder seal even with today's extreme high pressure turbo systems. These studs far exceed clamping forces provided by standard head bolts.
  • Reduced Head Gasket Failure: By replacing the factory head bolts with high-quality head studs, the risk of head gasket failure is significantly reduced, especially in high-performance or boosted applications.
  • Kit Includes - 12x Heads Studs, 12x Nuts, 12x Hardened Parallel Washer, 1x 9/16 12pt Socket, 1x 4mm Allen Wrench, 1x Fastener Assembly Lubricant & Instruction Manual. Black oxide finish protects from wear and tear. Hardened parallel washers allow for uniform load distribution and accurate torque readings.
