Maintain proper airbox drainage and engine protection with this Genuine Nissan Airbox Water Drain, designed for Nissan Patrol GQ TB42 EFI models. This OEM one-way drain valve is fitted to the bottom of the air filter box and allows water to safely escape while preventing dust, dirt, and contaminants from entering the intake system.

Over time, the original rubber drain can perish, harden, crack, or fall out completely due to heat, age, and harsh under-bonnet conditions. A missing or failed drain can create an open entry point for unfiltered air or water, risking engine damage—especially after water crossings or off-road driving.

Manufactured to genuine Nissan specifications, this direct-fit replacement ensures reliable sealing, correct drainage function, and long-lasting durability in tough Australian conditions.
