BC Brian Crower Valve Guides for EJ20/EJ25 WRX STi (BC3960/BC3961)

Valve guides are essential components that wear over time, particularly in high-revving EJ20 and EJ25 engines. To maintain proper tolerances and optimal performance, it's advisable to replace worn guides with new aftermarket ones. BC premium valve guides, made from Manganese Silicon Aluminum Bronze alloy, are CNC machined to precise tolerances. These guides resist cracking and corrosion, reduce friction, and ensure high lubrication even at elevated engine temperatures and RPMs. They are the ideal replacement for worn or damaged guides and are fully compatible with BC's lineup of stainless steel valves.
