Restore the correct seal around your idle air control system with this Genuine Nissan IACV-IAA Valve Bottom Gasket, designed to suit Nissan Patrol GQ Y60 models fitted with the TB42E EFI engine and GU Y61 models fitted with the TB45 petrol engine. This OEM gasket is fitted at the rear of the intake manifold where the IACV-IAA valve mounts, sealing the bottom of the valve assembly against the manifold to prevent air leaks and maintain correct idle control operation.

Over time, the original IACV-IAA valve gasket can harden, compress, crack, or deteriorate due to constant exposure to engine heat, vibration, and age. A damaged gasket can allow unwanted air leaks into the intake system, affecting idle quality, engine performance, and throttle response. Replacing it with a Genuine Nissan component restores the factory seal and helps maintain reliable idle air control operation.
