Seal the exhaust flange joint and keep hot exhaust gases where they belong with the MAHLE Exhaust Pipe Flange Gasket F31879. It installs as a direct-fit replacement across a wide Nissan and Infiniti range, covering the 2007-2018 Nissan Altima, 2009-2014 Nissan Maxima, 2009-2024 Nissan Murano, 2011-2016 Nissan Quest, 2013 Infiniti JX35, 2013-2022 Nissan Pathfinder, 2014-2016 Infiniti QX60, and 2016-2023 Nissan Maxima.
This gasket sits at the connection between exhaust pipe flanges, compressing between the mating faces to seal the joint against pressurized, high-temperature exhaust gas.
Signs this gasket may need replacing: a ticking or hissing exhaust leak at the flange, an exhaust smell, or soot around the joint. Diagnose the source before replacing, since these signs can have other causes. If a failed flange gasket is the cause, this replaces it.
