Review on 🚗 K&N Cold Air Intake Kit for 2005-2010 Jeep (Commander, Grand Cherokee, Grand Cherokee III) 5.7L V8 - High Performance, Increased Horsepower, 50-State Legal [Part Number: 57-1549] by Sean Purnomo

Purchased from Revain for use on the 2008 Jeep Grand Cherokee 5.7LI Highly Recommended! The item arrived on time but parts were missing. I'm not sure if K&N or Revain is to blame. I called K&N customer service and they shipped me the missing parts with great on the spot customer service. I installed my first K&N air intake on one of my cars a long time ago and have done it on every car I have owned since. Provides a deeper and angrier engine sound. Improved throttle response (how quickly the engine responds to my foot on the pedal) on every car I've fitted it to. Has given me the best gas mileage on any car I've installed it on. The improved airflow helps the engine run a little better on its own. I tend to use an air intake like this as the first step in modifying my car. On a large V8 this intake is a good match with a redesigned throttle body and high performance exhaust and pro tuned to a 91 octane rating. UPDATE ***** Still happy with this purchase! for several months and several thousand miles. The impact on fuel economy is negligible, but that's probably because I'm hitting the accelerator more often. Everyone who has driven or ridden my Jeep since installing this air intake has commented on how great the engine sounds. Combined with professional 91 octane tuning, BBK throttle body and Borla exhaust, this intake helps provide the airflow a big engine needs to breathe deeply.
