Detailed Description

This Gates emission hose is engineered for direct replacement in the crankcase ventilation system, helping restore proper hose routing and emission system operation. The molded rubber design follows the original shape and connection points, which is important for maintaining a secure seal and consistent airflow through the PCV/emission circuit. EMH298 is listed for a wide range of Honda and Acura models, including 2008-2017 Honda Odyssey, 2008-2012 Honda Accord, 2009-2011 Honda Pilot, 2013-2015 Acura RDX, and 2010-2014 Acura TSX.

This part cross-references Honda 11856R70A00 for the same application.

What It Helps Fix

• Cracked or hardened crankcase breather hose material
• Vacuum leaks at the valve cover or intake connection
• Broken or loose push-in hose ends
• Emission system flow issues caused by hose deterioration
• Rough idle or drivability concerns related to PCV hose leakage

Installation Notes and Tips

Verify the hose routing and end orientation before installation. Inspect the mating ports on the valve cover, PCV valve, and intake for damage or buildup, and replace any brittle adjacent hoses at the same time. Confirm the vehicle application by year, make, model, and position before ordering, since EMH298 is used in both valve cover to intake and PCV valve to intake locations depending on the vehicle.

Quality Assurance

Gates positions this hose as an OE-exact replacement within its Emission Control Hose line, using high-quality materials to support durability and service life in emission system service.
