57-1549 for the 2005, 2006 and 2007 Jeep Grand Cherokee 5.7 liter V8 engine and the 2006 and 2007 Jeep Commander 5.7 liter V8 engine. K&N dynamometer tests show an estimated 15.30 horsepower gain @ 5046 RPM. The chrome top K&N air filter (RF-1048) sits behind a powder coated steel heat shield which helps isolate it from the rest of the engine compartment. This combination allows for a steady supply of unrestricted airflow to reach the Jeep's engine providing an instant performance gain with no other modifications necessary.
K&N's air intake design provides excellent air filtration and lower restriction than the factory air box system. The heat shield assembly is installed into the engine bay using factory mounting points. The heat shield isolates the K&N air filter from the hotter temperatures around the engine and allows it to receive a consistent flow of fresh cooler air.
The chrome top of the large RF-1048 air filter stops dust and dirt by using multiple layers of cotton and 1.45 oz, of K&N filter oil. This high flow technology invented by K&N provides the best balance of airflow and filtration. Washable and reusable K&N air intake filters can go up to 100,000 miles before cleaning is required.
The 57-1549 can be easily installed in 90 minutes or less and is backed by the K&N Million Mile Limited Warranty. This intake is street legal in 50 states for the applications mentioned in this story.
