$24.99
Keep your PCV system sealed and crankcase vapors moving where they belong with the MAHLE PCV Valve Grommet (P/N B31873). It drops in as a direct-fit replacement across a range of Chrysler, Dodge, and Jeep applications, including the 2005-2008 Chrysler 300, 2007-2008 Chrysler Aspen, 2006-2008 Dodge Charger, 2004-2008 Dodge Durango, 2005-2008 Dodge Magnum, 2003-2008 Dodge Ram 1500, 2003-2008 Dodge Ram 2500, 2003-2008 Dodge Ram 3500, 2006-2008 Jeep Commander, and 2005-2008 Jeep Grand Cherokee.
- Seals and secures: holds the PCV valve in its mounting opening and maintains a sealed connection so crankcase vapors are routed through the PCV system rather than leaking out.
- Molded grommet: flexible design fits the factory opening for a snug seat.
- Common wear item: grommets can harden and crack with age and heat; if a deteriorated grommet is the cause of a vacuum leak or whistle, this replaces it.
A worn grommet lets unmetered air past the PCV connection, which can lead to a lean condition and rough idle. Installing a fresh grommet provides a tight seat for the PCV valve. Diagnose the cause of any driveability issue before replacing.
