2007-2009 Mustang GT500 K&N 57 Series FIPK Cold Air Intake 57-2571

Increase Your Horsepower With K&N's Air Intake

Air-Filter-Industry Leader K&N designed this 57-Series Generation II Air Intake (aka FIPK) especially for your Shelby Ford Mustang to give it a nice increase of horsepower and torque. Adding a cold-air intake is a perfect way to get some easy power and performance gains for your car and this one doesn't fail to impress. The 57-Series intake dramatically reduces intake restriction as it smooths and straightens air flow, allowing your GT500's engine to inhale a larger amount of air than the restrictive OEM stock air filter assembly. On top of their impressive power gains, this Cold Air Intake Kit improves your car's fuel economy and throttle response, making it one of the most effective upgrades you can do at this price point.

Performance K&N Filter with Heat Shield and Inlet Tube

When they designed their 57-Series kits, K&N dug up the largest air filter that they could possibly fit in place of your Mustang's factory air box and built the rest of the system around it. The filter is one of K&N's classic high-flow oiled systems that brings in a much larger volume of air than stock along with improved filtration. Along with the filter, each K&N 57-Series kit comes with a full heat shield assembly and a highly efficient inlet tube that works together to promote improved airflow into your ride's engine over the stock air box.

Installation Note: Included in this kit are detailed instructions for a relatively quick and easy installation (takes approximately an hour using standard tools).
