2003-2004 Mustang Mach 1 K&N FIPK Cold Air Intake 57-2555

Increase Your Horsepower With K&N's Air Intake

If you're looking to get a boost of horsepower and improved torque for your Mach 1, one of the best modifications you can do on a budget is to ditch that factory stock air filter and replace it with a cold-air intake. Air-Filter-Industry Leader K&N designed this 57-Series Generation II Air Intake (aka FIPK) especially for your Ford Mustang to give it a performance boost. Adding a cold-air intake dramatically reduces intake restriction as it smooths and straightens air flow, allowing your Mach 1's engine to inhale a larger amount of air than the restrictive OEM stock air filter assembly. On top of 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.

50-State Legal: This air filter meets the California Air Resource Board (CARB) regulations, making this modification street legal and ensures it is allowed for emissions testing. The CARB # is D-269-37.

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