The K&N 57-6011 Performance Air Intake System delivers more airflow to 2001-2004 Nissan Pathfinder V6 3.5L engines for guaranteed gains in horsepower and torque. This complete kit replaces the stock air filter and intake tube with a roto-molded HDPE tube paired to an oversized high-flow filter and custom heat shield. Installation takes less than 60 minutes using basic hand tools and improves engine response across the powerband.
Key Features
- Roto-molded HDPE intake tube: Enlarges airflow volume to the engine while resisting heat deformation for consistent performance.
- Oversized oiled cotton air filter: Washable and reusable design lasts up to 100000 miles between cleanings under normal highway driving.
- High-flow filtration traps dirt while allowing maximum airflow.
- Replaces factory air filter and intake tube without permanent modifications.
- Backed by decades of air intake engineering for Nissan vehicles.
- High-density polyethylene HDPE roto-molded tube and oiled cotton filter media for durability and performance.
