Is your Nissan Navara NP300 (D40 or D23) blowing black smoke or losing power? A cracked or leaking turbo intercooler hose might be the culprit. This is a direct replacement outer hose for that system. It's made from heat-resistant rubber and metal components designed to handle the pressure and high temperatures from the turbo. Replacing a failed hose can restore engine performance and reduce that ugly black exhaust smoke. The OE part number it replaces is 14463-4KV0A. It's about 39cm (15.35 inches) long with inner diameters of 6.5cm and 6cm. Please note, this is a non-OEM (aftermarket) part. Installation is straightforward if you're mechanically inclined (it's a direct swap), but professional installation is always recommended for turbo system work. Comes with one hose. A cost-effective fix for a common issue on these popular Nissan trucks.
