K&N Engineering knn57-6011

The K&N roto-molded cold air intake for 2001–2004 Nissan Pathfinder 3.5L increases intake volume to boost horsepower and torque while pairing a washable, reusable High-Flow oiled cotton filter with a custom molded tube and heat shield. The system is engineered for improved airflow and throttle response. The oversized conical filter can allow up to 100,000 miles between services under normal highway driving, and the kit typically installs in less than 90 minutes. K&N backs the system with its No-Hassle Lifetime Limited Warranty and notes it will not void vehicle warranty.
