If you're looking to kick your ride up a notch, you’re in the right place. The folks at Injen Technology have really nailed it with their PowerFlow (PF) intake system, and trust me, it’s not just marketing fluff. This thing is built to deliver some serious horsepower. I’ve seen dyno results that show gains of up to 13 hp and 14 lb-ft of torque, which is no small feat for a cold air intake. And let’s be real, who doesn’t want a little extra power under the hood?

The first thing you’ll notice is the 6061-T6 aluminum tubing. It’s not just for looks—though it definitely adds some style to your engine bay—but it’s designed for superior airflow. You can even choose from different finishes to match your vibe. Plus, Injen has thought through the placement of the air filter. It’s positioned to keep hot air out, ensuring your engine gets that cool, dense air it craves. This helps drop air intake temperatures, which is a big win for performance.

Installation? No sweat. The Injen PF intake kit comes with everything you need for a direct fit, so you won’t be hunting down extra parts or tools. And like all of Injen’s cold air intakes, this one comes with a limited lifetime warranty. That means you can hit the road with confidence, knowing that your investment is protected for as long as you own it.

Here’s what you get:

  • Dyno-proven gains of up to 13 hp and 14 lb-ft of torque.
  • Injen's patented MegaRam (MR) Technology for enhanced performance.
  • Power gains without the need for additional tuning—keeping your A/F ratios in check.
  • Durable 6061-T6 aluminum intake tubing.
  • A fully serviceable Injen SuperNano-Web dry air filter to keep things clean.
  • A more aggressive engine tone when you’re on the gas.
  • Smooth intake piping that reduces restrictions and boosts airflow.
  • Made right here in Pomona, California.
  • Backed by Injen’s Limited Lifetime Warranty.

Fitment:

  • Nissan Frontier (2005-2019)
  • Nissan Pathfinder (2005-2012)
  • Nissan Xterra (2005-2015)

So if you’re ready to unleash some serious power in your Nissan Frontier, Pathfinder, or Xterra, the Injen PF1957P Polished Cold Air Intake System is definitely worth checking out. It’s a solid upgrade that you can feel and hear, and it’s built to last.
