K&N 05 Nissan Pathfinder V6-4.0L Performance Intake Kit

If you're looking to get more out of your 2005-2019 Nissan Frontier, Pathfinder, or Xterra with the V6-4.0L engine, this K&N performance intake kit is a solid option. It's designed to help your engine breathe easier by replacing the restrictive factory airbox with a more efficient system. This means more air can get into your engine, which typically results in a noticeable boost in both horsepower and torque.

The kit features a rotationally-molded high-density polyethylene (HDPE) tube, which is shaped to help increase the volume of air flowing into your engine. It comes with K&N's well-known washable and reusable High-Flow Air Filter. This oversized, conical filter uses oiled cotton media to capture dirt while letting plenty of air through. Under normal highway driving, you can go up to 100,000 miles between servicing the filter. A custom heat shield is also included to help block hot air from the engine bay, ensuring your engine gets cooler, denser air for better performance. K&N backs this system with their Million Mile Limited Warranty.

Installation is usually straightforward and can often be completed in under an hour with basic tools. This intake is designed to be a direct replacement for your stock air intake system and will not void your vehicle's warranty.
