There are several brands out there when it comes to aftermarket air intake systems, but Injen leads the way in innovation, efficiency, and power gains. Injen PowerFlow Intake Systems are more than just a high flow air filter on a less restrictive tube. Featuring Injen's patented MR Technology, Injen incorporates a step process into their intake tubes (meaning they increase or decrease the diameter of the intake tube at strategic points to control airflow). This, coupled with the fact that Injen Power Flow Intakes incorporate your existing sensors, mean you won't have any check engine lights and it is safe for use on your vehicle. At the end of the Injen PowerFlow Intake is the Injen Power Box. In addition to providing additional filtration and heat protection, the Power Box houses a high flow Injen air filter that can be cleaned and reused for as long as you own the vehicle. An air stabilizer and incorporated velocity stack smooth out airflow to help maximize power gains. Comprehensive installation instructions including photos make installation of your new Injen Intake easy enough to do yourself with basic hand tools in under an hour. Injen Power Flow Air Intake Systems exceed OE standards and as a result will not void any existing factory warranties that you may have. Additionally, you'll enjoy increased horsepower and torque, as well as improved throttle response. Fuel economy gains, especially during freeway conditions, are commonly achieved helping the unit to pay for itself over time. The part number for this item is PF9006P or PF9006WB (depending on the color) and fits 2011-2017 Ford Explorer 3.5 Non Turbo models. If your vehicle is an "EcoBoost" version, this intake will NOT fit and you need to use Injen part number PF9005 instead.
