Beck/Arnley Engine Air Intake Hose P/N:158-1625
Beck/Arnley 158-1621 air intake hose for the 1996-2000 Nissan Pathfinder V6 3.3L and other vehicles carries intake air to the engine. Also called an engine air intake hose, this rubber bellows is an application-specific part.
Cracks or splits in the rubber folds, or an end that has come loose, can let air leak in and may show up as a rough idle or a warning light. Those signs have other causes too, so look the hose over with the engine off and cool before you replace it.
This hose is a direct replacement for OE applications and matches OE form, fit and function. It fits the 1996-2000 Nissan Pathfinder V6 3.3L, the 1997-2000 Infiniti QX4 V6 3.3L and the 2001 QX4 V6 3.5L, and each application calls for one hose.
