Vehicle Fitment:
Subaru EJ20/EJ25
2002-2014 Subaru WRX
2004-2021 Subaru STi
Specs:
Total Length: 1.873" / 47.57mm
Outer Diameter: 0.4357" / 11.07mm
Valve Stem Diameter: 6mm
More Info:
GSC Power-Division valve guides are made from a proprietary blend of Manganese Bronze and turned on dedicated precision CNC turning centers. With performance and aftermarket installation in mind, we hold extremely tight tolerances on through-hole concentricity to outside diameter which minimizes the required honing time for the installer. True-to-size outside diameters minimize honing of guide bosses on cylinder heads that don't require boss service. Our guides are easier to install and shaped to improve air flow instead of just copying OEM design.
