Maintain proper crankcase ventilation with this Genuine Nissan Front Breather Hose to Intake Pipe, designed to suit Nissan Patrol GU Y61 models fitted with the TB45 4.5L petrol engine. This OEM breather hose connects the top of the rocker cover to the rubber intake pipe leading to the throttle body, allowing filtered air to circulate through the engine's crankcase ventilation system for efficient engine operation.

Over time, the original rubber hose can harden, crack, split, or become brittle due to constant exposure to engine heat, oil vapours, and age. A damaged breather hose can create vacuum leaks, allow unfiltered air into the intake system, contribute to rough idling, reduced engine performance, increased fuel consumption, and oil residue within the engine bay. Replacing it with a Genuine Nissan component restores the factory crankcase ventilation system and helps maintain reliable engine performance.
