Description

Unlock your Nissan Maximaƒ??s full performance potential with the INJEN SP Series Air Intake System ƒ?? engineered specifically for 2004ƒ??2008 Maxima 3.5L V6 models. This high-performance system, part number SP1946BLK, is designed to deliver superior horsepower gains, increased throttle response, and a deep, aggressive engine tone that makes a statement.

Built around Injenƒ??s patented MegaRam (MR) Technology and Air Fusion tuning process, this intake system ensures safe, dyno-proven performance without compromising engine reliability. The smooth, mandrel-bent 6061-T6 aluminum tubing reduces turbulence and enhances airflow, creating a direct path to power while maintaining an optimal air/fuel (A/F) ratio across the RPM range.

At the heart of this intake is the SuperNano-Web Dry Air Filter, which offers unmatched filtration and airflow. It's fully washable, reusable, and engineered to last, making it a long-term upgrade to your engine bay.

This black-finished intake system also features a cold air configuration, helping to draw in cooler, denser air for enhanced combustion efficiency. The result? Improved engine response, fuel efficiency, and that satisfying intake growl when you step on the throttle.

Backed by Injenƒ??s Limited Lifetime Warranty, the SP1946BLK offers performance you can feelƒ??and reliability you can count on.

Key Features:

  • Direct fit for Nissan Maxima 2004ƒ??2008 3.5L V6
