Maintain proper crankcase ventilation and engine performance with this Genuine Nissan Breather Hose, designed for Nissan Patrol GQ Y60 models fitted with the TB42S engine. This OEM hose connects the rocker cover to the air intake system, allowing controlled ventilation of engine blow-by gases while helping keep the intake system clean and free from oil vapour contamination.

Over time, breather hoses are exposed to constant heat, oil vapours, and engine bay conditions that can cause them to harden, crack, or split. A deteriorated hose can lead to vacuum leaks, rough idle, poor engine performance, increased oil contamination in the intake, and excessive engine bay residue. Replacing a worn breather hose with a genuine Nissan part helps restore correct airflow and reliable engine operation.

Manufactured to genuine Nissan specifications, this direct-fit hose provides precise fitment, oil-resistant construction, and long-lasting durability, making it ideal for harsh Australian driving and off-road conditions.
