You can Select Your Vehicle to check if 7W7Z-6A664-AA fits your vehicle.

To prevent damage from high temperatures, all rubber and plastic hoses in the engine, accessory, and emission systems should be regularly inspected. When doing inspections, it is important to check for cracks, loose clamps, material hardening as well as leaks. Clamps must be tight enough not to leak anything. Hoses without clamps need an examination because they can expand or harden causing a leak. PCV system hose should be checked for such things like cracks, leaks, obstructions then cleaned if there is any blockage. Vacuum hoses should be labeled before removing them. A vacuum hose is going to help you determine where the air is leaking from. Deterioration chaffing and cracking are defects of flexible fuel lines that have to be detected. Fuel hoses designed for your system should be used here. Spring-type clamps require replacements with screw clamps instead. The bends at metal fuel lines contain creases or fractures which normally lead to their breaking off hence use seamless steel tubing for replacements where possible.

Vacuum hoses, often color-coded or identified by stripes, must have the same material properties when replaced. Plastic T-fittings should be inspected for cracks and hose distortion.
