Injen PF5014P PowerFlow Cold Air Intake System
Updated June 20, 2026
The Injen PF5014P is a polished aluminum cold air intake system engineered specifically for the 2014-2018 Jeep Grand Cherokee equipped with the 3.0L V6 Turbo Diesel engine. Part of Injen's PowerFlow (PF) series, this intake replaces the restrictive factory airbox with a free-flowing, heat-shielded design that draws cooler, denser air for improved combustion efficiency. It includes a reusable SuperNano-Web dry air filter and all necessary hardware for a direct-fit installation.

Design and Function
The PF5014P uses a polished aluminum intake tube and a heat shield to isolate the filter from engine bay heat. The filter is positioned in a cooler airflow zone, and the SuperNano-Web dry filter media provides high filtration without oil, reducing maintenance. The system is designed to minimize intake air temperature, which helps maintain air density and supports consistent power delivery.
Vehicle Fitment
This intake is a direct-fit upgrade for the 2014-2018 Jeep Grand Cherokee with the 3.0L V6 turbo-diesel engine (VM Motori A630). It is not compatible with gasoline engines or earlier model years. Note that this system is not CARB exempt and is not legal for sale or use on vehicles registered in California.
Performance and Features
Injen reports dyno-proven gains of up to 11 horsepower and 15 lb-ft of torque with the PF5014P. The polished aluminum construction resists corrosion and provides a show-quality finish. The dry filter can be cleaned and reused, and the kit includes a heat shield, silicone couplers, and stainless steel clamps for a secure, leak-free installation.
Installation Notes
The PF5014P is a bolt-on system that uses factory mounting points and requires no cutting or drilling. Injen includes detailed, illustrated instructions. Typical installation time is under an hour. The kit is designed to work with the stock turbo inlet and mass airflow sensor, so no tuning is required for normal operation, though a tune may maximize gains.
