Restore reliable crankcase ventilation and engine performance with this Genuine Nissan Front Breather Hose, designed to suit Nissan Patrol GQ Y60 models fitted with the TB42 EFI petrol engine. This OEM breather hose connects the rocker cover to the pipe running forward to the front of the intake manifold, helping maintain correct crankcase ventilation and engine vacuum operation.

Over time, the original rubber breather hose can become hard, brittle, cracked, or split due to age, engine heat, oil exposure, and constant heat cycling. A damaged breather hose can introduce unmetered air into the intake system, potentially causing rough running, poor engine performance, and issues with the crankcase ventilation system.

Manufactured to Genuine Nissan specifications, this front breather hose is designed with the correct factory bends, connections, and dimensions for precise fitment. It is the ideal replacement for a deteriorated or damaged factory breather hose when maintaining or restoring your Nissan Patrol GQ Y60 TB42 EFI.
