JamesF Posted November 30, 2006 Posted November 30, 2006 Can anyone tell me what the diameter of the breather pipes are on my Subaru (2004 WRX) ? I'm going to be fitting an Oil Catch Can and want to buy a breather filter but don't know what size I should get. I think it's 15mm but I'm not really sure. Thanks, James.
fai17 Posted November 30, 2006 Posted November 30, 2006 I used 15mm-16mm oil hose from Pirtek. You'll need 4 T- pieces too
Carl Davey Posted November 30, 2006 Posted November 30, 2006 Cam breathers are 1/2" (12.7mm []) on the Classic at least. IIRC the block breather is slightly larger. Not wishing to teach anyone to suck eggs but remember hose size is measured by internal diameter.
