Does this intake require an engine tune?

No, this Injen PowerFlow intake system features MR Technology, which is designed to provide performance gains and maintain air-fuel ratios without requiring an additional engine tune.

What is the benefit of the MR Technology?

MR Technology refers to Injen's patent-pending tuned intake tubing. The specific length and diameter of the tubing are engineered to optimize airflow and power delivery for your specific vehicle's engine, acting like a built-in performance enhancer.

How do I maintain the air filter?

The included SuperNano-Web dry air filter is fully serviceable. You can clean it and reuse it, and replacement filters are available separately if needed.

Product Details

If you're looking to give your 2005-2009 Jeep Grand Cherokee WK with the 4.7L V8 engine a bit more pep, this Injen PowerFlow cold air intake system is a solid option. It's designed to replace your restrictive factory airbox and tubing, allowing your engine to breathe more freely. This means you can expect improved throttle response and a more aggressive engine sound when you step on the gas.

The intake tubing is constructed from T6-6061 aluminum, polished for a clean look under the hood. Injen's MR Technology is built into the system, which means the tubing is tuned to specific lengths to optimize airflow and power gains without needing a separate engine tune. It comes with a serviceable SuperNano-Web dry air filter, positioned to draw in cooler, denser air from outside the engine bay, which helps increase torque and horsepower. Dyno testing shows gains of up to 12 horsepower and 13 lb-ft of torque.

This kit includes everything needed for a direct-fit installation, meaning no welding or complex modifications are required. It's backed by Injen's limited lifetime warranty, so you can be confident in its durability.
