This is a genuine Nissan replacement injector pipe for cylinder number four, specifically for Nissan Navara and Pathfinder models fitted with the YD25 diesel engine. This precision-engineered high-pressure pipe is located in the engine bay and is responsible for connecting the fuel rail to the injector for cylinder #1, ensuring correct fuel delivery.

Injector pipes are a critical fuel system component that can require replacement due to corrosion, fatigue from engine vibration, or internal contamination. A leaking or damaged pipe can result in a strong diesel smell, poor performance, and rough idling. Using a genuine Nissan part ensures a direct-fit replacement to restore the integrity of the high-pressure diesel system.

Product Features

• Genuine Nissan Quality: Guarantees perfect fitment, material integrity, and performance to OEM specifications.

• High-Pressure Durability: Manufactured from high-grade steel engineered to withstand the extreme pressures of a common-rail diesel system.

• Leak-Free Design: Precision-bent and flared to match factory tolerances, ensuring a reliable, leak-free seal at the injector and fuel rail.

• Safe & Reliable: Avoids the risks of inferior aftermarket pipes that can crack under pressure, leading to dangerous fuel leaks, poor performance, and potential engine damage.

Installation Notes 

Replacement is a job of moderate difficulty for an experienced DIY mechanic but is a straightforward task for a qualified workshop. Extreme care must be taken when working on high-pressure diesel fuel systems. You will need appropriate flare nut spanners to avoid rounding off the fittings. It is highly recommended to replace the associated injector seals when fitting a new pipe. This is also a good opportunity to inspect the other injector pipes for any signs of corrosion, leaks, or damage.
