Detailed Description

Gates EMH313 is an emission control hose engineered for crankcase ventilation service where the PCV valve connects to the intake. Its OE-exact construction helps maintain the original hose routing and fit, while the rubber material supports everyday engine-bay conditions. This hose is a direct replacement choice for 2003-2007 Infiniti G35, 2003-2008 Infiniti FX35, 2006-2008 Infiniti M35, and 2003-2006 Nissan 350Z applications listed for PCV valve to intake use.

What It Helps Address

• Cracked or split crankcase breather hose
• Vacuum leaks in the PCV-to-intake hose path
• Emission system performance issues caused by hose deterioration
• Improper crankcase ventilation flow from a damaged hose
• Fitment problems from a hose that no longer matches the original routing

Installation Notes and Tips

Confirm the hose route before installation and compare the original part to the EMH313 for length, end style, and diameter. This hose uses push-in ends and is molded to match the OE configuration, so proper seating at both connection points is important for a secure installation. Inspect nearby PCV and intake connections for wear before completing the repair.
