Keep crankcase vapors moving along their intended path with the Gates Engine Crankcase Breather Hose EMH291, an OE-exact emission control and ventilation hose. It routes blow-by gases between the valve covers (valve cover to valve cover) as a direct-fit replacement for the 2005-2019 Nissan Frontier, 2012-2018 and 2020-2021 Nissan NV1500, 2012-2018 and 2020-2021 Nissan NV2500, 2012-2018 and 2020 Nissan NV3500, 2005-2012 Nissan Pathfinder, and 2005-2015 Nissan Xterra. See the Buyer's Guide tab for engine-specific coverage.
Built to last: constructed from high-quality materials for durability and long service life.
Fluid resistant: resistant to fuel vapors and oil for the crankcase-ventilation environment.
Direct replacement: designed for an exact fit and easy installation.
Rated to spec: meets SAE J30R7 specifications with a temperature range of -40°F to +275°F (-40°C to +135°C).
By restoring the routing between the valve covers, this hose helps return the emission ventilation system to its intended operation. A cracked, hardened, or leaking original can let oil mist escape and disrupt crankcase ventilation; if a failed hose is the cause, this replaces it.
