What It Helps Address

• Emission system leaks at the valve cover-to-intake hose path
• Improper crankcase ventilation routing
• Broken or loose clip-on hose connection
• Service replacement for a damaged OE-style emission hose

Installation Notes and Tips

Verify the hose routing, end style, and measured dimensions before installation. Confirm the vehicle uses the valve cover to intake tube or valve cover to intake layout listed for EMH370, and inspect the mating ports for wear, debris, or damage before clipping the hose into place. Proper seating at both ends is important for maintaining a secure seal and correct emission system operation.
