Injen 06-09 FJ 4.0L V6 w/ Power Box Polished Power-Flow Air Intake System

The Injen Power-Flow (PF) intake system starts with 6061-T6 aluminum tubing, polished to a shine. This material choice isn't just for looks; it helps keep the intake charge cooler than steel would, and the smooth interior surface reduces airflow restrictions compared to the stock rubber tubing. This particular kit is designed specifically for the 2007-2009 Toyota FJ Cruiser with the 4.0L V6 engine, and it includes Injen's patented MR Technology, which is essentially a tuned intake tube designed to optimize airflow and air-fuel ratios without needing a separate engine tune. You'll get a more aggressive engine tone under acceleration, and Injen's dyno testing shows gains of up to 19 horsepower and 19 lb-ft of torque.

Installation is straightforward thanks to the included hardware and instructions, aiming for a direct fit onto your FJ Cruiser. The kit features a rotomolded air filter housing that works with Injen's twist-lock filter design, helping to shield the SuperNano-Web dry air filter from engine heat and drawing in cooler, denser air from the best possible location. This improved airflow can make a noticeable difference in throttle response and overall engine performance. The air filter is serviceable, and Injen backs this entire system with a limited lifetime warranty, so you can be confident in its long-term performance.
