The retro-styled Jeep Commander was designed new from the ground up, but there is no question about its heritage, one look and you know it's a Jeep. K&N Engineering developed a performance air intake system (57-1548) for 2006, 2007, 2008 and 2009 Jeep Commander and 2005-2009 Grand Cherokee models with the 4.7 liter V8 engine.

The K&N performance air intake system for the 2006 Jeep Commander 4.7 liter V8 is one of the first on the market for this vehicle. K&N tests have shown an estimated horsepower gain of 9.4 HP @ 4397 RPM with the 57-1548 intake.

"The horsepower gain is really good for a vehicle that does not have a mass air flow sensor," said K&N Performance Kit Manager Bert Heck. "The engine compartment is really busy and even though the Commander does not have a lot of open space our engineers were able to knock out a system that provides good power gains." The development side of 57-1548 was extensive when it boiled down to the design work, said Heck.

This air intake system uses a conical shaped chrome top high-flow air filter (RF-1048) and powder coated aluminum heat shield in place of the vehicle's stock air box. The result is an air filter that captures harmful particles, provides more surface area, improves air flow, and increases service life. This K&N air filter performs for up to 100,000 miles before service is required depending on driving conditions. Improving the air path between the filter and the motor is the rotationally-molded high-density polyethylene tube. It offers the most flexibility in design and outstanding horsepower numbers. It takes about 90 minutes or less to install this system with simple hand tools. It is covered by K&N's Million Mile Limited Warranty and is 50 state street legal.
