Upgrade your vehicle's airflow with the K&N Engineering 04-06 Nissan Altima and 04-08 Maxima performance intake kit. This system features a high-density polyethylene (HDPE) rotationally-molded tube designed to increase the volume of airflow to your engine, resulting in a guaranteed boost in horsepower and torque. Its durable construction ensures long-lasting performance, while the precise fitment makes installation straightforward and typically completed in less than 90 minutes. The kit is engineered to enhance engine efficiency and power delivery without compromising reliability or drivability.
The system includes a washable, reusable High-Flow Air Filter with oiled cotton filter media, allowing you to go up to 100,000 miles between filter services under normal highway conditions. The oversized, conical filter design maximizes airflow and filtration capacity, contributing to better engine performance and fuel efficiency. A custom heat shield is incorporated to protect intake air from the high temperatures of your engine bay, ensuring cooler, denser air reaches your engine for optimal combustion.
This intake kit is compliant with EPA standards and is protected by the K&N No-Hassle Lifetime Limited Warranty, providing peace of mind for long-term use. Please note that some intakes may not be legal for sale or use on pollution-controlled vehicles in California; refer to the product specifications for CARB status and compliance details specific to your vehicle. Designed specifically for select Nissan Altima and Maxima models, this performance intake kit offers an effective upgrade for enthusiasts seeking increased power, efficiency, and reliability from their vehicles.
