Injen FJ 4.0L V6 with Power Box Blk Power-Flow Air Intake System

Price:   $390.90

When it comes to unlocking your engine's explosive energy, timing is everything. Injen's Power-Flow Cold Air Intake is engineered to deliver a blast of oxygen at the perfect moment for blazing combustion and gut-wrenching power output.

While basic intakes merely force air down an engine's gullet, the Injen Power-Flow puts your motor on a steady diet of colder, richer oxygen. The process starts with the high-flow air filter's integrated Air Inducer, Air Stabilizer and Velocity Stack. Air is drawn in, smoothed out and pressurized.

From there, the oxygen flows through the Mega Ram-tuned pipe, where it gets released to the mass air flow senor at calculated intervals. Each kit goes through a rigorous dyno-testing process and fine-tuned to unleash ferocious performance across the RPM spectrum. Some vehicles come with a Power Box heat shield if needed.

Your Injen Power-Flow bolts on without any drilling for a simple at-home installation. Lifetime Warranty on tube and filter.


  • Equip your vehicle with the Injen Power-Flow-the world's first cold air intake that's truly custom-tuned for the drivetrain in your specific year, make and model
  • Injen spent a decade developing their Mega Ram (MR) Technology—a sophisticated tuning process that allows Injen to tweak the diameter and shape of the intake pipe for the greatest horsepower and torque gains
  • Each vehicle goes through a thorough dyno-testing process to ensure maximum performance
  • The first step along the Power-Flow Cold Air Intake's pathway to power is the high-flow air filter, with its fully integrated Air Inducer, Air Stabilizer and Velocity Stack
  • The Power-Flow Cold Air Intake's air filter is engineered to pull in more oxygen, strip out turbulence and pressurize it to the ideal level
  • The inline calibration intake of your Injen Power-Flow Cold Air Intake controls the air speed and releases it through the mass air flow sensor at precisely calculated intervals
  • All of the advanced designs on your Injen Power-Flow Cold Air Intake deliver fierce acceleration, lighting-fast throttle response and consistent power gains across the entire RPM range
  • Its tuned tube is wrought from aerospace-grade, lightweight, anti-corrosive T-6 aluminum
