Subaru PCV Valve 2004-2008 WRX/2004+ STI

  • The Positive Crankcase Ventilation (PCV) valve keeps crankcase gasses from building up inside your valve covers, while keeping foreign stuff out. This inexpensive part is important! A broken or clogged PCV can cause excess blow-by or blown seals from too much crankcase pressure.  Fits 2004-2005 WRX, and most 2.5L turbo EJ25 cars through 2014, including 2006-2009 WRX; plus 2004-2019 STI. Does NOT fit 2010-2014 WRX.
