Detailed Product Information

This emission control hose is part of Gates’ Emission Control Hose line, which is built around OE-exact replacement fit and material selection. EMH318 is intended for the crankcase ventilation path between the PCV valve and intake, helping maintain the original hose routing on Nissan Frontier, Nissan Pathfinder, Nissan Xterra, and Nissan NV1500, NV2500, and NV3500 models. The hose uses rubber construction and a push-in end design to match the factory-style connection layout, while the included protective sleeve adds an extra layer where the hose is exposed to heat and wear.
