What This Hose Helps Address

• Cracked or brittle crankcase breather hose material

• Improper crankcase ventilation routing on OE-style service repairs

Installation Notes

Verify the end style, centerline length, and inside diameter before installation. The EMH145 uses molded plastic construction with push-in and clip-on ends, so the original routing and connector engagement should be matched carefully during service. Confirm the vehicle’s emission configuration, especially on applications noted for PCV valve to intake or valve cover to intake tube routing.
