What It Helps Address

• Cracked or brittle crankcase breather hose material
• Broken clip-on connections at the emission hose ends
• Incorrect hose routing in the valve-to-secondary-air-pump circuit
• Vacuum or ventilation leaks caused by worn emission hose components
• Emission system performance issues related to damaged hose passages

Installation Notes and Tips

Verify the hose routing, connector count, and end style against the original part before installation. Confirm the 16 mm inside diameter and 9.5 in. centerline length match the vehicle’s factory layout, and inspect adjoining connectors for wear or damage before attaching the new hose. EMH226 uses clip-on ends and does not include a protective sleeve.
