Maintain proper engine performance and prevent vacuum leaks with this Genuine Nissan Plenum Manifold Halves Gasket, designed for Nissan Patrol GU Y61 models fitted with the TB48 engine. This OEM gasket seals the joint between the upper plenum manifold halves, ensuring correct air delivery, stable fuel mixture, and smooth engine operation.

Over time, the original gasket can dry out, harden, or shrink due to heat cycling and engine age. A failing plenum gasket may cause vacuum leaks, rough idle, poor fuel economy, hesitation under acceleration, or inconsistent engine performance. Replacing the gasket helps restore proper sealing integrity and ensures the TB48 engine operates as intended.

Manufactured to genuine Nissan specifications, this direct-fit replacement provides precise fitment, durable sealing performance, and long-lasting reliability for towing, touring, off-road, and everyday driving conditions.
