Enhance your 2007-2009 Ford Mustang Shelby V8-5.4L with the K&N Engineering 57-2571 performance cold air intake kit. This system features a high-density polyethylene (HDPE) rotationally-molded tube that increases airflow to your engine, resulting in a guaranteed boost in horsepower and torque. The design ensures improved engine efficiency and responsiveness during high-performance driving. The included washable, reusable High-Flow Air Filter, with oiled cotton media, allows for up to 100,000 miles of service under normal highway conditions, reducing maintenance intervals and costs. Its oversized, conical shape maximizes airflow capacity and provides excellent filtration, helping to optimize engine performance over time. A custom heat shield is incorporated to safeguard intake air from engine bay heat, maintaining cooler, denser air for better combustion and power output. Installation typically takes less than 90 minutes, making it an accessible upgrade for enthusiasts and DIYers alike. As part of K&N's commitment to quality, this intake system is backed by a No-Hassle Lifetime Limited Warranty, guaranteeing durability and performance. Compatible with EPA standards, it is an excellent choice for drivers seeking to improve their vehicle's horsepower, torque, and overall driving experience while remaining compliant with emissions regulations. Please refer to product specifications for CARB status if you plan to use it in California or other pollution-controlled regions.
