The K&N 03-04 Ford Thunderbird V8-3.9L Performance Intake Kit is a high-performance air intake system designed to enhance engine airflow and boost power output. Constructed with a high-density polyethylene (HDPE) rotationally-molded tube, it ensures increased airflow volume, leading to guaranteed gains in horsepower and torque. The kit features a washable, reusable High-Flow Air Filter with oiled cotton media, and its oversized, conical design allows for up to 100,000 miles of service under normal highway conditions. A custom heat shield is included to protect intake air from high engine bay temperatures, and the entire system can typically be installed in less than 90 minutes, making it a durable and efficient upgrade for performance enthusiasts.
This intake kit is specifically designed for 2003-2004 Ford Thunderbird models equipped with a 3.9L V8 engine. It serves as a direct bolt-on replacement, providing improved airflow and performance without requiring extensive modifications. Compatibility with pollution control regulations varies, so some intakes may not be legal for sale or use on pollution-controlled vehicles in California; users should check the CARB status for their specific vehicle. The kit includes the intake tube, heat shield, and high-flow filter, making it suitable for street and daily driving applications where increased engine efficiency and power are desired.
