K&N 00-04 Nissan Xterra V6-3.3L Performance Intake Kit

If you're looking to get more out of your 1999-2004 Nissan Frontier or 2000-2004 Xterra with the V6-3.3L engine, this K&N performance intake kit is designed to help. It replaces your restrictive factory airbox with a system that allows your engine to breathe more freely, which can lead to a noticeable improvement in power. This kit is built to increase airflow, and K&N guarantees it will boost both horsepower and torque.

The intake tube is made from high-density polyethylene and is rotationally molded to help maximize airflow volume. It's paired with K&N's washable and reusable High-Flow Air Filter, which uses oiled cotton media. The oversized, conical shape of the filter means you can go up to 100,000 miles between cleanings under normal highway driving conditions. A custom heat shield is included to help keep hot engine bay air away from the intake, ensuring cooler, denser air enters the engine for better performance. K&N backs this kit with their Million Mile Limited Warranty.

Installation is typically straightforward and can often be completed in under an hour, with no special tools required beyond basic hand tools. This kit is designed as a direct replacement for your stock air intake system.
