Keep your engine's crankcase ventilation flowing along its intended path with the SKP PCV Valve / Engine Crankcase Breather Hose (SK121107). This OE-style part installs as a direct-fit replacement across a broad range of Audi and Volkswagen applications, including the 2008-2013 Audi A3 [L4-2.0L], 2009-2014 Audi A4 [L4-2.0L], 2011-2012 Audi Q5 [V6-3.0L], 2008-2014 Volkswagen GTI [L4-2.0L], and 2009-2014 Volkswagen Tiguan [L4-2.0L] — see the Buyer's Guide tab for the full list of covered years and engine codes.
The crankcase breather hose carries blow-by vapors through the crankcase ventilation system, helping route those gases through the intended path and limit oil-mist escape. If a cracked, collapsed, or leaking hose is behind a rough idle, a whistling vacuum leak, or oil seepage, this replaces the failed hose.
This item is cataloged under both names — PCV Valve and Engine Crankcase Breather Hose. Country of origin: China. Manufacturer part number SK121107.
