Product Description

The K&N 57-2519-3 Performance Air Intake System is engineered specifically for the 1996-2004 Ford Mustang GT equipped with the 4.6L V8 engine. It replaces the restrictive factory air box and intake tubing with a high-flow HDPE intake tube, oversized oiled-cotton filter, and protective heat shield designed to reduce intake-air temperatures and increase airflow. These improvements yield measurable gains in horsepower and torque, while remaining fully legal for road use.

Installation is straightforward, requiring only basic hand tools and utilizing existing factory mounting points. The design retains your factory mass-air-flow sensor and original calibration, so no ECU retuning is necessary. With the washable filter rated for up to 100,000 miles between servicing, this kit offers both performance and longevity. Backed by K&N's No-Hassle Lifetime Limited Warranty, it's built to last.

Fitment is confirmed for model years 1996-2004 on the Ford Mustang GT with the 4.6L V8 engine and rear-wheel drive. Because this is an older platform, and 2025 coverage is not relevant, no newer years apply. Be sure to verify that your vehicle has the 4.6L V8 SOHC engine and GT trim before purchase.
