K&N 99-04 Ford Mustang V6-3.8L Performance Intake Kit
Increase Your Horsepower With K&N's Air Intake
If you're looking to get a boost of horsepower and improved torque for your Ford Mustang, 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 Mustang's engine to inhale a larger amount of cooler 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.

K&N Performance Filter with Heat Shield and Tube
When they designed their 57-Series kits, K&N brought in 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. Another nice feature is that the air filter is washable and reusable, saving you money over the life of your car as you won't have to purchase a new one at regular maintenance intervals.
