Overview

The Xotic Performance CP882 is a head stud kit designed for Subaru Impreza WRX STI DOHC engines. It is compatible with EJ20 2.0L and EJ25 2.5L turbo engines.

Constructed from Xotic 7200 alloy steel, these head studs offer superior tensile strength compared to 8740 chromoly steel, rated at 220,000 psi. The black oxide finish provides protection against wear and tear, while hardened parallel washers ensure uniform load distribution for accurate torque readings.

Show original supplier description

The Xotic Performance CP882 head stud kit is a direct-fit replacement engineered to unleash more performance from your Subaru Impreza WRX STI. This kit is specifically designed for all Subaru Impreza WRX and STI TURBO EJ20 2.0L and EJ25 2.5L DOHC Turbo Engines. Constructed from Xotic 7200 alloy steel, these head studs offer ultra strength with a tensile rating of 220,000 psi, surpassing the capabilities of 8740 chromoly steel. The threads are rolled after heat treatment for optimal fatigue strength, providing ample clamping force to prevent cylinder heads from lifting, even under extreme high-pressure turbo systems. This design significantly reduces the risk of head gasket failure, particularly in high-performance or boosted applications. The kit includes a comprehensive set of 12 head studs, nuts, and hardened parallel washers, along with a 9/16 12pt socket, a 4mm Allen wrench, fastener assembly lubricant, and a detailed instruction manual with diagrams. The black oxide finish on the studs and hardware protects against wear and tear, while the hardened parallel washers ensure uniform load distribution for accurate torque readings.
