Is your stock shift boot torn, or otherwise worn out? Replace it with a brand-new factory-issue shift boot from Subaru.
Fits all 2005 manual-transmission Subaru WRX.
2002-2004 boots had provisions for bolts to hold the boot, while the 2005 style does not, but we have had customers make it work as it is the same size.
Sorry, the 2002-2004 boots are discontinued.
