Product Details

The Gates Emission Control Hose line focuses on replacement hoses that follow original equipment dimensions and connection style. EMH110 is built to restore crankcase ventilation flow and emission system routing where the factory hose has cracked, hardened, or lost its seal.

This part cross-references KCV-112 and XR3Z 6A664 AA for the same application.

What It Helps Fix

• Cracked or split crankcase breather hose
• Vacuum leaks at the valve cover to intake tube connection
• Rough idle caused by damaged emission hose routing
• Unstable crankcase ventilation flow
• Emission system faults related to deteriorated hose material

Installation Notes and Tips

Verify the hose path, end style, and dimensions before installation. EMH110 uses push-in ends and molded construction, so the original routing should be matched closely during replacement. Inspect the mating ports on the valve cover and intake tube for wear, debris, or damage before seating the hose.

Fits 1999-2004 Ford Mustang, valve cover to intake tube. Confirm the vehicle’s emission hose layout against the original part before ordering.
