Installation Notes and Tips

Verify the hose routing, end styles, and dimensions before installation. The EMH170 uses a clip-on end and a push-in end, so inspect the mating connectors for wear, debris, or damage before fitting the new hose. Confirm the valve cover to air cleaner position on your Ford Focus and replace any brittle adjacent connectors if needed to ensure a secure seal.

Quality Assurance

Gates builds this emission control hose as an OE-exact replacement using durable plastic and rubber materials to support long service life and proper system operation. The molded construction and protective sleeve help the hose maintain its shape and resist premature wear in normal engine-bay conditions.
