Injen 05-19 Nissan Frontier 4.0L V6 w/ Power Box Polished Power-Flow Air Intake System

If you're looking to give your 2005-2019 Nissan Frontier with the 4.0L V6 engine a bit more pep, this Injen Power-Flow air intake system is a solid choice. It's designed to replace your restrictive factory airbox and tubing with smoother, larger-diameter components that help your engine breathe easier. This means you can expect a noticeable improvement in throttle response and a more aggressive engine sound when you step on the gas.

The system features polished 6061-T6 aluminum tubing, which not only looks sharp under the hood but also helps maintain a smooth path for air entering the engine. Injen has incorporated their patented MR Technology, which tunes the intake tract to optimize airflow and maintain the correct air-fuel ratios without needing a separate engine tune. The rotomolded air filter housing is designed to keep hot engine bay air out, feeding cooler, denser air to the engine for improved performance. It also includes a serviceable Injen SuperNano-Web dry air filter that uses a twist-lock design for easy removal and cleaning.

This kit comes with everything you need for a direct-fit installation, including all the necessary hardware and instructions. While the CARB E.O. applies to 2005-2008 models, the performance benefits are available for all listed applications. You'll also get the peace of mind that comes with Injen's limited lifetime warranty.
