Upgrade your Ford Mustang GT 5.0L V8 with the K&N 63-2578 enclosed cold air intake system, designed for optimal airflow and horsepower gains. The system features an enclosed air box construction that protects the filter and inlet air from engine bay heat, ensuring cooler, denser air reaches your engine for improved performance. The air box lid allows for quick and tool-free filter access, making maintenance convenient and efficient. The high-density polyethylene (HDPE) rotationally-molded tube increases airflow volume, which translates into a guaranteed increase in horsepower and torque. This durable construction resists warping and provides long-lasting performance under demanding driving conditions. The included high-flow, washable, and reusable oiled cotton filter boasts an oversized, conical design that can extend service intervals up to 100,000 miles under normal highway driving conditions, reducing maintenance time and costs. The entire system can typically be installed in less than 90 minutes, making it a practical upgrade for enthusiasts and daily drivers alike. While some intakes are not legal for sale or use on pollution-controlled vehicles in California, this system is engineered to improve engine efficiency and power output. The K&N guarantee includes a No-Hassle Lifetime Limited Warranty, offering peace of mind with every installation. Designed specifically for 2011-2014 Ford Mustang models with a 5.0L V8 engine, this intake kit is an excellent choice for those seeking enhanced performance without extensive modifications. Please verify CARB status for your vehicle, as some parts may not be CARB-compliant. Enhance your Mustang's performance and enjoy a more responsive driving experience with this high-quality, engineered intake system from K&N Engineering.
