K&N's air intake system for 2007, 2008, and 2009 Ford Mustang Shelby 5.4L
Ford Shelby Mustang gets estimated 53.7 extra horsepower with K&N air intake system
K&N Engineering has designed a performance air intake system (57-2571) that is street legal in 50 states for 2007, 2008, and 2009 Ford Mustang Shelby with the 5.4 liter V8 engine. K&N dynamometer testing shows an estimated 53.7 horsepower gain at 5900 rpm.

One of the reasons for such a high increase in horsepower is the large free-flowing K&N chrome top air filter (RF-1048). The factory air box is restricted in size and restrictive in air flow especially at higher RPMs. K&N designed a larger intake tube that fits nicely under the front stabilizer.
The tube is oval because the throttle body is also oval. This design means the cross section is larger. The estimated 53.7 horsepower gain is also aided by the radius adaptor's design as it smoothly takes the 6 inch flange of the air filter and mates it with the air intake tube.
The heat shield isolates the filter element from the heat of the engine which results in an immediate flow of cooler air for additional power. It takes less than 90 minutes to install this K&N air intake system. This intake will eliminate much of the air path restriction and let your engine breathe freely. K&N air intake systems come with the famous K&N Million Mile Limited Warranty.
It’s easy to think of a Corvette V8 when you think of the 2006, 2007 and 2008 Chevrolet Trailblazer. The SUV packs a Corvette-derived 6.0 liter V8 that can handle a zero-to-sixty acceleration in 5.7 seconds. Take a look at our 57-3061 features video to see dyno testing in progress.

K&N was able to get the additional horsepower by replacing the restrictive original factory air box with an aerodynamic designed air intake. The design of the intake's heat shield directs cooler outside air toward the K&N chrome top air filter (RF-1032). This specially designed heat shield isolates the K&N air filter from the engine heat. The air intake fits into the engine compartment using factory holes and mounting points.
The high flow technology invented by K&N and made in the USA provides the best balance of airflow and filtration. The RF-1032 is also washable and reusable and can go up to 100,000 miles before cleaning is necessary.
The 57-3061 can be easily installed in 90 minutes or less and is backed by the K&N Million Mile Limited Warranty. Take a look at our 57-3061 installation video to see all the steps involved.

K&N dynamometer tests show a 15.42 horsepower gain at 2911 RPM with the
57-3000. This air intake system has a lid that goes on top of the heat shield and includes a full air box.
The K&N air intake system filters harmful dirt and debris from entering the engines of these diesel work trucks. The heat shield isolates the K&N air filter (RC-5139) from the engine heat. This in turn keeps a cooler air charge going into the engine for an instant power gain. No other modifications are necessary.
The high flow technology invented by K&N and made in the USA provides the best balance of airflow and filtration. The
RC-5139 is also washable and reusable and can go up to 100,000 miles before cleaning is necessary.
The 57-3000 K&N air intake system can be easily
installed in 90 minutes or less with simple hand tools. The K&N air intake system is backed by the K&N Million Mile Limited Warranty.

The 57-1550 features a specially molded intake tube and a large K&N air filter. The air filter, RP-4660, fits into the stock location. Cooler outside air is directed toward the K&N air filter from the factory fresh air duct.
K&N developed a new heat shield for this particular engine and designed the tube to accommodate front wheel drive and the transmission. The electronic components under the hood were repositioned with the new design of the PT cruiser. The heat shield isolates the K&N air filter from the engine heat. This in turn keeps a cooler air charge going into the engine for an instant power gain.
The high flow technology invented by K&N and made in the USA provides the best balance of airflow and filtration. The RP-4660 is also washable and reusable and can go up to 100,000 miles before cleaning is necessary.
The 57-1550 can be easily installed in 90 minutes or less and is backed by the K&N Million Mile Limited Warranty.
