What It Helps Fix

• Emission system faults related to hose deterioration
• Loose or damaged clip-on hose ends

Installation Notes and Tips

Verify the vehicle year, make, model, and engine configuration before ordering, especially on 2017-2018 Ford Taurus applications without SHO engine. Inspect the mating ports on the valve cover and intake tube for damage or buildup before installing the new hose. Confirm the hose routing matches the original path so the molded shape and 17-inch centerline length seat correctly.
