Installation Notes and Tips

Verify the hose routing, end orientation, and connection points before installation. This EMH140 uses clip-on ends and molded geometry, so correct alignment at the valve cover and intake connections is important for a secure seal. Inspect adjacent breather components and replace any worn seals or connectors during service to avoid repeat leaks.
