PRODUCT SPECIFICATIONS

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. Centerless ground to assure perfect concentricity.

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.
