This is a genuine Nissan intercooler to throttle body hose, specifically for the Nissan Navara D40 and Pathfinder R51 models fitted with the V9X 3.0L V6 diesel engine. This hose is located on the right-hand (driver's) side of the engine bay and forms a critical part of the air induction system, connecting the intercooler outlet pipe directly to the throttle body inlet.

Over time, the original hose can perish, split, or crack from constant exposure to boost pressure, heat, and oil vapour. A damaged hose will cause a boost leak, leading to symptoms like a noticeable loss of power, increased turbo lag, a hissing sound from the engine bay, and excessive black smoke from the exhaust under load. Replacing a failing hose is essential to restore engine performance and prevent unfiltered air from entering your engine.

Product Features

• Genuine Nissan Quality: An authentic OEM part, guaranteeing a perfect fit and long-term reliability for your V9X engine.
• Direct-Fit Replacement: Designed as a direct replacement for the original hose, ensuring a straightforward installation without modifications.
• Durable Construction: Manufactured from high-quality, heat and oil-resistant materials engineered to withstand high boost pressures and demanding Australian conditions.
• Restores Performance: Eliminates boost leaks to restore lost engine power, improve throttle response, and ensure optimal fuel efficiency.

Installation Notes 

Replacement is a straightforward job for a competent home mechanic with basic hand tools. Access to the hose clamps can be tight, so patience is key. It is highly recommended to inspect the original hose clamps for wear or corrosion and replace them if necessary. Before fitting the new hose, ensure the connecting surfaces on the intercooler pipe and throttle body are clean and free of oil residue to guarantee a secure seal.

Nissan Genuine Parts

Choosing genuine Nissan parts ensures the quality and fit for your Nissan. Unlike some aftermarket alternatives, genuine Nissan parts are manufactured to exacting standards, using materials specifically designed to withstand the rigors of Australian conditions. Guaranteeing performance, service life, and reliability. Cheaper aftermarket hoses often use inferior materials that can't handle the V9X's boost pressure, leading to premature splitting or degradation. This not only causes performance issues but also risks engine damage from unfiltered air and debris entering the intake.
